hmmmm
i dont know any vocaloid stuff 😢
but some kpop and non kpop would do maybeee...?
ITZY, BabyDONTcry, ahof, SKZ (their newer songs) , And maybe StayC?
For non kpop i like these: AmiiFy, byjaye, clairo, beabadoobee, sodiken (i dont remember their name sorry) and Syko!

Honorable mention is COSMOSY! i cant classify them in jpop, non kpop or kpop because they make somgs in english kr and jp all at once, so i consider them Global instead, and XG can be anothee but they make english songs so theyre global-pop instead. :3
