I will list the ones i remember.
Kyeaintdead. (All of his songs are different in their own way)
Black sabbath.
Obkatiekat.
Apricot froot.
Mori calliope.
Anri.
Doom Eternal.
(Any kind of heavy metal i can find)
That's all i remember.
it depends on the song.
i sometimes watch them but there are way too many people chatting all at once meaning nobody is going to see any of my chats.
also the more low budget private vtubers can get away with saying things that hololive can't.
