96neko is the first that comes to mind, as does Soraru.
Mafumafu's voice is pretty nice too. Love the high peaks he's known for haha
nqrse, Tightson, and Alilem I like for their rap skills.
Then there's KOOL, Gero (who some ppl compare my voice with his in my covers), and Glutamine I love how crazy he gets haha.
What sort of utaites do you like? I know a lot of old school.
