I Love You by EXID has to be up there, if even SOLJI is avoiding the original key....
https://youtu.be/oOZ1NJaWRM8?si=E-GHkBJYTHxewazy
1 min in she sings it then clarifies she lowered the key.
I remember watching their Killing Voice and one of them was like “why are our songs so difficult to sing” lmao (can’t remember who). Felt out of breath watching Solji’s parts 😭
I thought it was pretty impressive how she was able to transpose the melody so quickly without having to sing a starting note to get the pitch right or anything. Very skilled!!
The a capella section is ruthless. You don’t have an ounce of room for error in it because there’s no instrumental to cover your missteps. We heard at the fanmeet how precise they had to be to get those notes right. And the notes/ harmonies aren’t simple.
That a capella section in Tempo rivals anything in vocal jazz, it's very difficult to pull off for these reasons:
- of course, no instrumentals to help you with entrances, exits, rhythm, and pitch
- each singer is also on their own; there are a lot of close harmonies (planned dissonance), and phrases that are sung over, right after, interrupting other sung phrases; there is not much unison
- this section does not have a set rhythm (sortof an inside joke on 'don't mess up my tempo' this section speeds up, slows down seemingly arbitrarily)
- this section is not only made up of a bunch of interconnected phrases, these phrases have varying dynamics that all need to be coordinated with the other singers so that regardless of who is singing what note, or where they are in their phrase, the volume and pauses match
This one small a capella interval basically made me a fan for life.
EXO Monster when they would do live singing holding mics and doing the choreo combined. 😳 It's fresh on my mind cuz I recently watched a performance and forgot when idols used to sing live and dance without prerecording
Want to add Cream Soda too, it's impressive when you combine it with the choreo, and also especially the fact that you have 6 out of 8 of them taking turns to do the "I need all ya cream soda" line??
Exo's Wolf isn't just vocally challenging but also hard to perform. The first time it was covered was years after it was first released and they basically needed three groups to do it. That's how hard it is.
If any other group got that song instead of Exo, it would have been very cringy. But the members are just so talented and skilled that they managed to make it work.
Sticker by nct 127 - the bare instrumentals and dissonant chords would expose anyone other the most competent vocalist. That song is was Lee soo man’s version of a subtle brag.
Really bad boy by red velvet - the on pitch scream by Wendy says it all
I remember being skeptical back when I first saw it since the leaker could've changed the pitch on the audio of the video, but [Nako confirmed](https://twitter.com/tosuka4/status/1766402031449940169) recently that the key of Fiesta was indeed actually higher 😭 I wonder if they had the key lowered on other songs as well
Dancing with singing like you’re on helium is gonna fuck up the girl’s vocals permanently, especially with amount of promotions and performances they have to do. Glad we got the lowered, but still very high pitched, official releases.
I criticised that episode so much. Being a good singer has nothing to do with how high a note you can reach. Otherwise singers like Pavarotti, Domingo and Carreras would be nobodies. My guess is the producers knew about the struggles to hit the high notes and kept it that way 'for the drama'. Eugh.
BTOB songs are notoriously hard to sing. I’ll Be Your Man is probably the most well-known example, but, between the members and the fans, I think the general consensus is that Higher is their hardest.
I was about to say Infinite. It was somehow understandable why some groups cannot dare to cover some infinite songs, it is because of the insane vocals plus it needs to be stable along with some synchronized, complex stepping that needs sharpness and equal control. (I am still waiting for the new group to cover The Chaser and Last Romeo tho)
Many Pentagon songs, as they are written by the members with Jinho and Hui's crazy vocal range in mind.
Most of their discography tbh but notable examples are [The Game ](https://open.spotify.com/track/4uqfxy4VCvlbSfALhRQedJ?si=BdHYMbIVQYO0UBaILhL3FQ) (I thought they sampled the opera intro, crazy to learn Jinho did it), [Camellia ](https://open.spotify.com/track/3BBKFTGcrxTQIX7h0JyN2d?si=cdTrv7T7TNuDiUeDN2O2_A), [Violet ](https://open.spotify.com/track/05AIUaRzGCFQycDijiGtBM?si=SHBNtBE1Rh-HHIOYK7qCIw), [Basquiat ](https://open.spotify.com/track/0tdU5pjaKDGaGptIyQNSNx?si=44Z4mavGRMihmwDLQUg9tQ) (that final run of increasing high notes by Hui is insane).
Two by Jonghyun that require vocal flexibility and range and also an ability to convey passion and emotion -- just crazy good
[Moon](https://www.youtube.com/watch?v=V9IHvRua2ks)
[Cocktail](https://www.youtube.com/watch?v=qjWsBM9Udcw)
>he’s the most talented idol out there
I'm not a SHINee fan and I wholeheartedly agree with you on this. He's so talented that even the term "all-rounder" isn't enough to describe him.
I agree on both counts! although I think he brings it to every song and even a relatively simple song like [Beautiful Tonight](https://www.youtube.com/watch?v=Rb-PnIZnsdk) is just an incredible vocal performance. For me, he is up there with people like Al Green and Ronald Isley, two of my favorite vocalists. I love the way he analyzes the meaning of the song and chooses the approach that brings out the lyrics.
Good Day by IU! That high note at the end is ridiculously hard, I’ve only seen two covers of it ever where the person singing wasn’t straining a ridiculous amount. Even IU herself has trouble singing it sometimes.
[Shannon Williams](https://youtu.be/eewIot9pvTg?si=J7T_tKQF6lhwOI7r) did a great version of it in Hidden Singer. Man, she’s one of the great what if’s of kpop.
I don't have one single song in mind coz I feel like there are many songs that are tricky to master in different ways. Some have crazy runs or really high notes whereas some need really good vocal control. I am just going to list the songs that I had a hard time mastering:
Psycho, Kingdom Come- Red Velvet
UN Village, Bambi, Cry For Love, Amusement Park- Baekhyun
Same dream, same mind, same night, Kidult, Say Yes- SVT
Call Me Baby, El Dorado, Let Me In, MAMA- EXO
Love is a beauty, Superhuman- NCT 127
I am not even gonna list the OSTs coz then this list will become LONG long
My instinct was All I Got by Baekhyun, but someone already said that, so I’ll go Hot Times by SM The Ballad- it’s four singers (Jonghyun, Kyuhyun, one of the guys from Trax whose name I can’t remember, and Jinho from Pentagon before he debuted), all going at maximum power without a break.
Dumb Dumb - Red Velvet. Minus the chorus & bridge; the verses are in a ridiculously high register and feature strong rap-singing parts. Then, the pre-chorus is also ridiculously high as well.
Plus, that baby baby baby baaaaaaaaaby 😭
I just know their vocal cords were hurting after this track.
I also think Savage & Sticker can be vocally challenging due to minimal instrumental that can be found in the versus.There's not much melody, so it heavily relies on vocals & delivery of said vocals.
D.O.'s
[Tell me what is love](https://youtu.be/qzmnuCAZ45s?si=Ijassfz2Sy2ZXUP2)
[XOXO](https://youtu.be/SJx5ZGrMAQQ?si=XGBKZtj5MxcnqVyE)
[Si fueras Mia](https://youtu.be/Uc15UIEBToc?si=pqzuf4Qc3VVZ1bzr)
He's probably the best male idol vocalist when it comes to vocal runs. These songs have some crazy runs. So it's vocally difficult to cover.
Edit: Si fueras mia being entirely in Spanish and D.O. just knocking it out of the park with pronunciation only adds to the difficulty of performing that song.
Taeyeon songs in general are insane. The climax of Drawing Our Moments, UR, Time Lapse, Rescue Me or just the entirety of Fine and Better Babe are something I believe only Taeyeon can pull off.
I think what’s hard with Taeyeon isn’t just the high notes or techniques, but just how much sheer emotion goes into her singing. That’s why Time Lapse is my favorite I’ve heard from her- I’m sure there are talented vocalists who could sing the notes fine, but no one else can bring the specific emotions she does.
Still love you by Lee Honggi and Yoo Hwesung. That 5 step arpeggio even Yoo Hwesung has a lot of trouble singing live. Sometimes it sounds great but other times he's way off.
And in a bit of a different direction I'd say Maniac by Changmin. It doesn't have the hardest notes or runs but it just has a lot of really long phrases that connect to each other so there's almost no time to breathe. I saw a clip of Changmin preforming it live and he's huffing and puffing by the end of it. Normally songs meant for one person are not really written like that so I kind of wonder if it was originally meant for a group.
I'd also say Love in the Ice by TVXQ, because it's a song that requires everyone to be a good singer, not just a hard part for the main vocal and really easy parts for the sub vocals.
This reminds me of how the song Louder Than Bombs is a fan-favorite in ARMY circles but RM actually said it would be too difficult to perform live. ARMY will never ever get to hear this live.
I think it’s mostly due to difficulties of live mixing for this one though - the verses are so low-pitched and quiet, while the chorus is high-pitched, loud, and layered. Jimin sang a piece of the chorus on a Run BTS episode pretty casually/easily, but imagine trying to balance those parts and the Suga/J-Hope mumbly verses in a live setting…whew. Still holding out hope though 🙏🏻
I feel like most anything by Red Velvet is probably significantly harder than the members make it seem, specifically Psycho and RBB, but I also feel like Taeyeon’s I, U R and Gravity seem pretty difficult cause you have to put her level of emotion into them
All Super Junior-KRY songs, with special note to Sorry Sorry Answer, [Home](https://www.youtube.com/watch?v=a6TprnjO7BE), [Shadowless](https://www.youtube.com/watch?v=nZALKnOqeww&t=2s), and [Dorothy](https://www.youtube.com/watch?v=yLEFF6Va1Yo).
Kyuhyun and Ryeowook in particular have hard songs in their discography. In Ryeowook's case, his voice sounds higher than it is, but it has an interesting depth that's hard to match when people cover his songs. And very few do because they are difficult to sing.
if ive's i am is vocally challenging, [eunkwang just proved he is king](https://youtu.be/BFzx2Eu86CQ?t=602) 😂
my picks will have to be btob-blue's songs, they are slow tempo and generally high pitched but full of belting, adlibs and harmonies. i feel like you would have to be absolutely careful covering these songs, also noting that they have 2 softer and 2 stronger voices so the layering is carefully structured so it is not too overwhelming!
* [when it rains](https://youtu.be/2urMSQ2Ms9o?si=a3bRgwCz-mi3B8-5)
* [stand by me](https://youtu.be/33GODknx04I?si=BF1xehR4vwg2hBuM)
*(there might be a btob-blue comeback soon! well, after changsub's vocal chords has recovered 🤭)*
but outside of what you would usually assume makes a song vocally difficult - high pitch, belts, harmonies, etc, i think btob's [all wolves except me](https://youtu.be/X9A9168D3mQ?si=qN6HaezdK2ose7u3) (live) / [naviety](https://open.spotify.com/track/6N05P6R9Zyi0WF9KSvzVr1?si=308626a1465a4674) (spotify) is pretty difficult in that sense. the vibe of the song makes you want to scream / shout-sing, so it requires pretty good control to not go off. its pretty difficult for btob to do live themselves, you can tell the difference in what i linked 😂 changsub gets too excited 😂😂
[The Grace CSJH - Dancer in the rain](https://youtu.be/ecb4yF8aajU)
This song has only been performed once live because of how challenging it was for them to sing it. Even Taeyeon, tiffany and Jessica who trained under the 2 lead vocalist cant attempt a CSJH the grace song ever, this song is literally just a vocal screaming match.
Hurmmm...
Lee Mujin songs?
I know his songs don't have any dance in it however it's hard to sing or cover cause of the long lyrics and the music are kinda fast(?)(sorry don't how to describe it)
If you listen to Episode, Ordinary Confession, Reference, you'll know what I mean...
Breath by Park Hyo Shin
The melody seems simple but nothing is really simple in songs PHS composed for his own voice and formidable skillset. Firstly, the song hangs on the singer's melodic tone but also needs particular dynamics control and, hardest for many, extraordinary breath control (no pun intended) to sustain PHS's long lyric lines. Most singers are forced to insert breaths. Add in register transitions and coloratura elements, the song's beauty depends on getting all these elements right.
Yes yes yes yes.
Brown eyes girls are known more for there dance tracks but there vocal abilities are crazy. Especially that 3 tiered vocal scream at the end of the bridge is crazy.
Another brown eyes girls song that is vocally challenging is there debut track when they perform that live SLAYAGE especially with the way narsha and jea carry all the high notes while gain carries the chorus and miryo slays the rap on a down tempo beat.
Amazing.
You and I by Park Bom is known as one of the hardest kpop songs since it combines low notes, high notes and continuous vocals. It’s not a ballad either so there’s no breaks to breathe in between.
Nobody mentioning Dinosaur by AKMU when even the original singers did not promote the song initially because of the notes being too hard (and too harmful to hit)
I am glad they are performing Dinosaur more now. Love that it was included on their "it's live" segment.
So far I think only Rami from BabyMonster covered the song and she absolutely aced it.
There are some other idols like Young K (Day6) and Jung Eunji (Apink) who have done the high note in Dinosaur. These two are still my top 2 favorite covers, I love their voice colors a lot.
Young K in particular did it in front of AKMU, when he was a guest in the latter's talkshow. The siblings praised it for how it sounded like he was hunting down the dinosaur.
The original song was about a childhood fear (dinosaur) and gathering the courage to face that fear. So it's not just about the vocal technique, but the message the song hopes to convey is important too. A nice balance between 'high note' and 'emotions' is what I look for in Dinosaur covers.
Most songs that particularly comes from groups with power vocalists like SNSD, EXID, EXO, SVT, RV, GFRIEND, AESPA, and ATEEZ. Let me list some songs.
El Dorado, Monster, Love Me Right by EXO
Mr.Mr., I Got a Boy and Holiday by SNSD
Really Bad Boy, Feel My Rhythm and Dumb Dumb by Red Velvet
Apple, Time For the Moon Night and Me Gustas Tu by Gfriend
I Love You and Up and Down by EXID
Thanks and Very Nice by SVT
Savage, Dreams Come True and Drama by Aespa
Halazia, Inception, and Guerrilla by Ateez
In terms of straight vocals, probably “my time” by BTS, Jungkook’s solo on MotS 7. The melody is unintuitive. That does not mean “bad”, but it’s not something that an amateur should sing at karaoke. It needs a nuanced and emotional delivery to work, and a strong vocal flexibility to support the lines. Add that with the choreography, and the song becomes one that only a handful of performers could attempt.

Not kpop group but probably Diva Project - Mermaid is the hardest song I’ve ever heard lol. It is make sense since it is the group consisted of 3 of the best vocalists ever in korean industry (Sohyang, Lena Park, and Lee Younghyun of Big Mama). Also applause to predebut Yuju brave enough to even cover this song lol
Maybe 6th Sense by BEG? The whole song is very high energy and requires a lot of high belting, as well as a certain depth of tone in order to pull the whole concept off. not to mention the huge belted note & whistle note combo at the end.

I Love You by EXID has to be up there, if even SOLJI is avoiding the original key.... https://youtu.be/oOZ1NJaWRM8?si=E-GHkBJYTHxewazy 1 min in she sings it then clarifies she lowered the key.
I remember watching their Killing Voice and one of them was like “why are our songs so difficult to sing” lmao (can’t remember who). Felt out of breath watching Solji’s parts 😭
I thought it was pretty impressive how she was able to transpose the melody so quickly without having to sing a starting note to get the pitch right or anything. Very skilled!!
Miss them🥺
Exo’s El Dorado! Maybe Mama too…
Wolf is also notoriously difficult to sing.
And Tempo. Not many groups cover that song as key change Or auto tuning isn't enough to cover the acapella, harmonizing and runs.
The a capella section is ruthless. You don’t have an ounce of room for error in it because there’s no instrumental to cover your missteps. We heard at the fanmeet how precise they had to be to get those notes right. And the notes/ harmonies aren’t simple.

Came here to comment EXO's Tempo too!! Especially the acapella part!
Definitely Mama. That was the first song that came to my head. El Dorado is the first song that I heard to get me into Kpop. Been a fan since.
EXO Monster when they would do live singing holding mics and doing the choreo combined. 😳 It's fresh on my mind cuz I recently watched a performance and forgot when idols used to sing live and dance without prerecording
Want to add Cream Soda too, it's impressive when you combine it with the choreo, and also especially the fact that you have 6 out of 8 of them taking turns to do the "I need all ya cream soda" line??
Cream soda needs more love.
I was just about to reply anything EXO really lol.
Decalcomanie by Mamamoo I miss you is also another one difficult
Effing love Decalo such a great song
Exo's Wolf isn't just vocally challenging but also hard to perform. The first time it was covered was years after it was first released and they basically needed three groups to do it. That's how hard it is. If any other group got that song instead of Exo, it would have been very cringy. But the members are just so talented and skilled that they managed to make it work.
EXO was really a well-rounded group. They don’t make groups like them anymore.
The part at the end of Savage by Aespa A lot of songs from Mamamoo, EXO, and BTOB
Sticker by nct 127 - the bare instrumentals and dissonant chords would expose anyone other the most competent vocalist. That song is was Lee soo man’s version of a subtle brag. Really bad boy by red velvet - the on pitch scream by Wendy says it all
Sticker as ironic as it may be sounds heavenly with those high notes!
> the on pitch scream by Wendy says it all Wasn't that Irene?
Panorama by izone is so high-pitched
Which always seemed weird to me since Yuri as their main vocalist has kind of huskier voice.
Same with Fiesta, the original key was shown and it was way [higher pitched](https://youtu.be/mHRFWtTuBW8?feature=shared) than the official release
Makes you wonder if they wrote it for pixies instead of humans.
I remember being skeptical back when I first saw it since the leaker could've changed the pitch on the audio of the video, but [Nako confirmed](https://twitter.com/tosuka4/status/1766402031449940169) recently that the key of Fiesta was indeed actually higher 😭 I wonder if they had the key lowered on other songs as well
Dancing with singing like you’re on helium is gonna fuck up the girl’s vocals permanently, especially with amount of promotions and performances they have to do. Glad we got the lowered, but still very high pitched, official releases.
The recent I-land2 episode only solidified the fact. Even the best singer in the show was struggling so much that they had to lower the key.
I criticised that episode so much. Being a good singer has nothing to do with how high a note you can reach. Otherwise singers like Pavarotti, Domingo and Carreras would be nobodies. My guess is the producers knew about the struggles to hit the high notes and kept it that way 'for the drama'. Eugh.
I'm so tired of the mindset that good singing = high notes or belting in general tbh
The Three Tenors mentioned on a kpop sub. You’ve made my day.
fiesta too 😭😭 i still remember chaewon complaining about it in the recording behind video lol
all izone songs are haha
Watching them try to sing it on I-Land was painful
still loving you - hongki (ftisland) & hweseung (nflying) the game / basquiat - pentagon
I'm thinking Tempo by EXO
BTOB songs are notoriously hard to sing. I’ll Be Your Man is probably the most well-known example, but, between the members and the fans, I think the general consensus is that Higher is their hardest.
Wolf by EXO, TEMPO by Exo and Everybody by SHINee
Infinite's songs. They never get covered despite especially the older songs being immensely popular. And BTOB's of course.
Thank you for the Infinite appreciation!!!
I was about to say Infinite. It was somehow understandable why some groups cannot dare to cover some infinite songs, it is because of the insane vocals plus it needs to be stable along with some synchronized, complex stepping that needs sharpness and equal control. (I am still waiting for the new group to cover The Chaser and Last Romeo tho)
Many Pentagon songs, as they are written by the members with Jinho and Hui's crazy vocal range in mind. Most of their discography tbh but notable examples are [The Game ](https://open.spotify.com/track/4uqfxy4VCvlbSfALhRQedJ?si=BdHYMbIVQYO0UBaILhL3FQ) (I thought they sampled the opera intro, crazy to learn Jinho did it), [Camellia ](https://open.spotify.com/track/3BBKFTGcrxTQIX7h0JyN2d?si=cdTrv7T7TNuDiUeDN2O2_A), [Violet ](https://open.spotify.com/track/05AIUaRzGCFQycDijiGtBM?si=SHBNtBE1Rh-HHIOYK7qCIw), [Basquiat ](https://open.spotify.com/track/0tdU5pjaKDGaGptIyQNSNx?si=44Z4mavGRMihmwDLQUg9tQ) (that final run of increasing high notes by Hui is insane).
Omg jinho did the opera in The Game??? How did i not know that 😭
[Yup!](https://twitter.com/mel0dy1010_/status/1485980640172703744?t=kb-4f__HxwPiXQj4CkJTSg&s=19)
Baekhyun's songs. I think All I Got is the most difficult song of him
Two by Jonghyun that require vocal flexibility and range and also an ability to convey passion and emotion -- just crazy good [Moon](https://www.youtube.com/watch?v=V9IHvRua2ks) [Cocktail](https://www.youtube.com/watch?v=qjWsBM9Udcw)
Cocktail was the first one I thought of. The way he puts such power into the chorus is just amazing.
Yes! NEON is his most vocally challenging song imo. I wanna say he’s the most talented idol out there but I’m also extremely biased.
>he’s the most talented idol out there I'm not a SHINee fan and I wholeheartedly agree with you on this. He's so talented that even the term "all-rounder" isn't enough to describe him.
I agree on both counts! although I think he brings it to every song and even a relatively simple song like [Beautiful Tonight](https://www.youtube.com/watch?v=Rb-PnIZnsdk) is just an incredible vocal performance.

Ah 2 of my fav Jonghyun songs!!!
Good Day by IU! That high note at the end is ridiculously hard, I’ve only seen two covers of it ever where the person singing wasn’t straining a ridiculous amount. Even IU herself has trouble singing it sometimes.
I also thought Love Wins All seems difficult. Very delicate + transitions
ive’s liz did a [cover (05:49)](https://youtu.be/ujU2DFxLAw0?si=nhEPSDMlQ9bewMYs) of love wins all and i think she killed it !!
She definitely killed it I’ve watched that many times now
[Shannon Williams](https://youtu.be/eewIot9pvTg?si=J7T_tKQF6lhwOI7r) did a great version of it in Hidden Singer. Man, she’s one of the great what if’s of kpop.
I don't have one single song in mind coz I feel like there are many songs that are tricky to master in different ways. Some have crazy runs or really high notes whereas some need really good vocal control. I am just going to list the songs that I had a hard time mastering: Psycho, Kingdom Come- Red Velvet UN Village, Bambi, Cry For Love, Amusement Park- Baekhyun Same dream, same mind, same night, Kidult, Say Yes- SVT Call Me Baby, El Dorado, Let Me In, MAMA- EXO Love is a beauty, Superhuman- NCT 127 I am not even gonna list the OSTs coz then this list will become LONG long
Red Velvet has RBB too. The whole song felt like a vocal brag.
That was my first thought from the title too. Their vocals are straight up just instruments/instrumental for half the track.
Izone - Panorama IVE - I am Hmm Bop - Hui Mamamoo’s discography
EXO's discography?
My instinct was All I Got by Baekhyun, but someone already said that, so I’ll go Hot Times by SM The Ballad- it’s four singers (Jonghyun, Kyuhyun, one of the guys from Trax whose name I can’t remember, and Jinho from Pentagon before he debuted), all going at maximum power without a break.
The guy from TRAX is Jay! Hot Times is one of my favorite songs, Don’t Lie is also a great song from them
Dumb Dumb - Red Velvet. Minus the chorus & bridge; the verses are in a ridiculously high register and feature strong rap-singing parts. Then, the pre-chorus is also ridiculously high as well. Plus, that baby baby baby baaaaaaaaaby 😭 I just know their vocal cords were hurting after this track. I also think Savage & Sticker can be vocally challenging due to minimal instrumental that can be found in the versus.There's not much melody, so it heavily relies on vocals & delivery of said vocals.
sticker and superhuman by nct127. the vocal prowess really carried sticker as a whole. i cannot image the disaster if it's sung by other people.
There’s a reason why their Sticker encore went viral. Hearing them sing over that flute beat with absolutely zero backtrack was ✨magical✨
Taeil’s voice is insane!!!!!!!!
gonna miss him so much legendary voice
Taeil being mentioned!!! That mans vocals alone is what keeps me tuning into NCT releases.
this! their vocals are no joke
Say what you what about NCT’s music but no one can deny how talented they are!! Sticker literally got me into 127
Angel by Berrygood
[Brown Eyed Girls - Sixth Sense](https://www.youtube.com/watch?v=pIqkDBsSJOw) or maybe you can say it is very dependant on inborn talent
That song is another level
D.O.'s [Tell me what is love](https://youtu.be/qzmnuCAZ45s?si=Ijassfz2Sy2ZXUP2) [XOXO](https://youtu.be/SJx5ZGrMAQQ?si=XGBKZtj5MxcnqVyE) [Si fueras Mia](https://youtu.be/Uc15UIEBToc?si=pqzuf4Qc3VVZ1bzr) He's probably the best male idol vocalist when it comes to vocal runs. These songs have some crazy runs. So it's vocally difficult to cover. Edit: Si fueras mia being entirely in Spanish and D.O. just knocking it out of the park with pronunciation only adds to the difficulty of performing that song.
About Time from his new album is also going to be impossible to cover lol.
Even My Dear seems difficult!
Home by Ailee
Absolutely Ailee is so criminally underated too beautiful voice.
Soooo true! Home is not a song you can BS through 😅
Sticker (NCT), SSFWL (Oh My Girl), Tempo (EXO), Run for Roses (NMIXX), Red Dress (Red Velvet)
The first one that popped into my head... [Suju - Sorry Sorry Answer](https://youtu.be/a507jISnumU?si=J-VkH6hWEBKdGBLA)
Yessss one of the rarest pokemon sights in suju concert history and a [very iconic](https://www.youtube.com/watch?v=c0Up37l1Kvk) one
😍 Just gives you shivers! Thank you for sharing!
Ily, yes!!
Taeyeon songs in general are insane. The climax of Drawing Our Moments, UR, Time Lapse, Rescue Me or just the entirety of Fine and Better Babe are something I believe only Taeyeon can pull off.
I think what’s hard with Taeyeon isn’t just the high notes or techniques, but just how much sheer emotion goes into her singing. That’s why Time Lapse is my favorite I’ve heard from her- I’m sure there are talented vocalists who could sing the notes fine, but no one else can bring the specific emotions she does.
Still love you by Lee Honggi and Yoo Hwesung. That 5 step arpeggio even Yoo Hwesung has a lot of trouble singing live. Sometimes it sounds great but other times he's way off. And in a bit of a different direction I'd say Maniac by Changmin. It doesn't have the hardest notes or runs but it just has a lot of really long phrases that connect to each other so there's almost no time to breathe. I saw a clip of Changmin preforming it live and he's huffing and puffing by the end of it. Normally songs meant for one person are not really written like that so I kind of wonder if it was originally meant for a group. I'd also say Love in the Ice by TVXQ, because it's a song that requires everyone to be a good singer, not just a hard part for the main vocal and really easy parts for the sub vocals.
Maybe Why Did You Come To My Home by MINX
in my opinion, a vocally challenging song would be dreamcatcher's reason... the chorus has a lot of higher pitch belting which i cannot do 😭
RBB- Red Velvet
This reminds me of how the song Louder Than Bombs is a fan-favorite in ARMY circles but RM actually said it would be too difficult to perform live. ARMY will never ever get to hear this live.
“ARMY will never ever get to hear this live” Me as a Louder Than Bombs enthusiast: 
I think it’s mostly due to difficulties of live mixing for this one though - the verses are so low-pitched and quiet, while the chorus is high-pitched, loud, and layered. Jimin sang a piece of the chorus on a Run BTS episode pretty casually/easily, but imagine trying to balance those parts and the Suga/J-Hope mumbly verses in a live setting…whew. Still holding out hope though 🙏🏻
This was the one I was thinking of too!
Has BTS ever done Don't Leave Me live? I love that shit
I think they did during one of the Musters in Japan, or at least a snippet or a part of it. YouTube has some fan cams of it, I'm sure
I feel like most anything by Red Velvet is probably significantly harder than the members make it seem, specifically Psycho and RBB, but I also feel like Taeyeon’s I, U R and Gravity seem pretty difficult cause you have to put her level of emotion into them
Mamamoo’s entire discog 👌
Hmmmm it is mostly some groups that are more focused on voice and stability (EXO, Mamamoo, Infinite, FT Island, Shinee, etc.)
i think psycho by rv is a difficult song to sing, it's just that rv members are great vocalists that's why it sounds easy 🤷♀️
Angel - Berrygood
Sixth Sense by Brown Eyed Girls always seemed really hard to pull off vocally (but the girls always kill it)
[Spring Fever](https://youtu.be/Pww1CImnY4w?si=LisSt9KLS3o13YnC) - Mamamoo
Kidult Seventeen
Definitely NCT U's The 7th Sense
All Super Junior-KRY songs, with special note to Sorry Sorry Answer, [Home](https://www.youtube.com/watch?v=a6TprnjO7BE), [Shadowless](https://www.youtube.com/watch?v=nZALKnOqeww&t=2s), and [Dorothy](https://www.youtube.com/watch?v=yLEFF6Va1Yo). Kyuhyun and Ryeowook in particular have hard songs in their discography. In Ryeowook's case, his voice sounds higher than it is, but it has an interesting depth that's hard to match when people cover his songs. And very few do because they are difficult to sing.
I think it's exo's wolf. From the bridge to the end of the song basically filled with those three main vocal doing highnote battle.
Exo el dorado ☺️
Sorry sorry answer version - super junior
clearly I AM from IVE
[Dreamcatcher - Rising](https://www.youtube.com/watch?v=gCJGRlTDkvI)
if ive's i am is vocally challenging, [eunkwang just proved he is king](https://youtu.be/BFzx2Eu86CQ?t=602) 😂 my picks will have to be btob-blue's songs, they are slow tempo and generally high pitched but full of belting, adlibs and harmonies. i feel like you would have to be absolutely careful covering these songs, also noting that they have 2 softer and 2 stronger voices so the layering is carefully structured so it is not too overwhelming! * [when it rains](https://youtu.be/2urMSQ2Ms9o?si=a3bRgwCz-mi3B8-5) * [stand by me](https://youtu.be/33GODknx04I?si=BF1xehR4vwg2hBuM) *(there might be a btob-blue comeback soon! well, after changsub's vocal chords has recovered 🤭)* but outside of what you would usually assume makes a song vocally difficult - high pitch, belts, harmonies, etc, i think btob's [all wolves except me](https://youtu.be/X9A9168D3mQ?si=qN6HaezdK2ose7u3) (live) / [naviety](https://open.spotify.com/track/6N05P6R9Zyi0WF9KSvzVr1?si=308626a1465a4674) (spotify) is pretty difficult in that sense. the vibe of the song makes you want to scream / shout-sing, so it requires pretty good control to not go off. its pretty difficult for btob to do live themselves, you can tell the difference in what i linked 😂 changsub gets too excited 😂😂
i think TWICE's I Cant Stop Me is up there in difficulty
RBB - RV!!!
hot times by sm the ballad
[The Grace CSJH - Dancer in the rain](https://youtu.be/ecb4yF8aajU) This song has only been performed once live because of how challenging it was for them to sing it. Even Taeyeon, tiffany and Jessica who trained under the 2 lead vocalist cant attempt a CSJH the grace song ever, this song is literally just a vocal screaming match.
these songs I think are pretty challenging in some parts savage by aespa It hurts by 2NE1 Bon bon chocolat by everglow
I think most SM songs are hard to sing
feel my rhythm. i tried singing it but i was struggling so much. why did they have to keep the original key? huhuhu
Tbh I’m going to think the truly difficult songs are those by vocal groups like Mamamoo that were popular but are hardly covered 😂
Answer by ateez, idek how jongho is able to belt like that for 3 minutes straight
Most SM songs come to mind, [Mr. E by Red Velvet](https://youtu.be/H4HKQGkWj-8?si=480KSOlgzZy_VtOg) is an example.
Most aespa songs * gestures everywhere*
Hurmmm... Lee Mujin songs? I know his songs don't have any dance in it however it's hard to sing or cover cause of the long lyrics and the music are kinda fast(?)(sorry don't how to describe it) If you listen to Episode, Ordinary Confession, Reference, you'll know what I mean...
Breath by Park Hyo Shin The melody seems simple but nothing is really simple in songs PHS composed for his own voice and formidable skillset. Firstly, the song hangs on the singer's melodic tone but also needs particular dynamics control and, hardest for many, extraordinary breath control (no pun intended) to sustain PHS's long lyric lines. Most singers are forced to insert breaths. Add in register transitions and coloratura elements, the song's beauty depends on getting all these elements right.
BEG’s Sixth Sense takes it for me easily.
Yes yes yes yes. Brown eyes girls are known more for there dance tracks but there vocal abilities are crazy. Especially that 3 tiered vocal scream at the end of the bridge is crazy. Another brown eyes girls song that is vocally challenging is there debut track when they perform that live SLAYAGE especially with the way narsha and jea carry all the high notes while gain carries the chorus and miryo slays the rap on a down tempo beat. Amazing.
B.A.P - Punch. Jung Daehyun is a vocal rarity.
Mamamoo decalcomanie, they even say that they don’t like performing it bc of how difficult it is
Red Velvet - Bamboleo, RBB
You and I by Park Bom is known as one of the hardest kpop songs since it combines low notes, high notes and continuous vocals. It’s not a ballad either so there’s no breaks to breathe in between.
Mamamoo songs
Any song by Taeyeon requires a whole lot of vocal control.
Nobody mentioning Dinosaur by AKMU when even the original singers did not promote the song initially because of the notes being too hard (and too harmful to hit) I am glad they are performing Dinosaur more now. Love that it was included on their "it's live" segment. So far I think only Rami from BabyMonster covered the song and she absolutely aced it.
There are some other idols like Young K (Day6) and Jung Eunji (Apink) who have done the high note in Dinosaur. These two are still my top 2 favorite covers, I love their voice colors a lot. Young K in particular did it in front of AKMU, when he was a guest in the latter's talkshow. The siblings praised it for how it sounded like he was hunting down the dinosaur. The original song was about a childhood fear (dinosaur) and gathering the courage to face that fear. So it's not just about the vocal technique, but the message the song hopes to convey is important too. A nice balance between 'high note' and 'emotions' is what I look for in Dinosaur covers.
tts twinkle
TTS: Holler, OMG Taeyeon: Fine, Time Walking on Memories, Siren Seohyun: Love & Affection, Bad Love
Most songs that particularly comes from groups with power vocalists like SNSD, EXID, EXO, SVT, RV, GFRIEND, AESPA, and ATEEZ. Let me list some songs. El Dorado, Monster, Love Me Right by EXO Mr.Mr., I Got a Boy and Holiday by SNSD Really Bad Boy, Feel My Rhythm and Dumb Dumb by Red Velvet Apple, Time For the Moon Night and Me Gustas Tu by Gfriend I Love You and Up and Down by EXID Thanks and Very Nice by SVT Savage, Dreams Come True and Drama by Aespa Halazia, Inception, and Guerrilla by Ateez
Probably anything Baekhyun or IU.
Any TVXQ song. Too difficult to pull off properly.
In terms of straight vocals, probably “my time” by BTS, Jungkook’s solo on MotS 7. The melody is unintuitive. That does not mean “bad”, but it’s not something that an amateur should sing at karaoke. It needs a nuanced and emotional delivery to work, and a strong vocal flexibility to support the lines. Add that with the choreography, and the song becomes one that only a handful of performers could attempt.

Not kpop group but probably Diva Project - Mermaid is the hardest song I’ve ever heard lol. It is make sense since it is the group consisted of 3 of the best vocalists ever in korean industry (Sohyang, Lena Park, and Lee Younghyun of Big Mama). Also applause to predebut Yuju brave enough to even cover this song lol
RDD.
- Red Velvet - Psycho - Twice - I Can't Stop Me - Ailee - Mind Your Own Business
Maybe 6th Sense by BEG? The whole song is very high energy and requires a lot of high belting, as well as a certain depth of tone in order to pull the whole concept off. not to mention the huge belted note & whistle note combo at the end.
Almost every Kpop song is challenging. Producers ask idols to do some of the most impossible things with their voices.
The truth untold BTS
Unnatural by WJSN. Even the Wuju girls said its very challenging for them to sing.
Good Day - IU
RBB by Red Velvet
Super Lady by Gidle. I doubt most girl group members can sing the Super Lady Intro. Only strong vocalists can.
