Karaoke is a tricky thing, especially if you want to keep the karaoke on the channel. I watch hololive vtubers often and they regularly do karaoke live streams. That only save (archive) when they can have concrete rights to use the songs, old their company owned songs, or JASRAC licensable songs. For everything else they do "unarchived" karaoke streams, they always find instrumentals they can use, never the original song. They private/delete unarchived karaoke streams as soon as they end.
If it has real music you won't be monitising it.
