Throwing some vtubers in the ring, since they cover a bunch of stuff. Won’t post more beyond this since you’re just googling popular vk/ vk anisong covers and seeing what it spits out. Below is about half-mil and up for view count.
星街すいせい (Hoshimachi Suisei) (Hololive) covering シド (SID) - 乱舞のメロディ(Ranbu no Melody):
空星きらめ (Sorahoshi Kirame) (Nijisanji) covering Janne Da Arc - ヴァンパイア (Vampire):
緑仙 (Ryushen) (Nijisanji) covering Acid Black Cherry - 黒猫 〜Adult Black Cat〜:
They had a whole Golden Bomber festival.
*I’m also assuming by acts this means more prominent artists/bands, so I don’t have to shill the Hard Off guy for the millionth time.
Ok, shilling Nagata-san. God of gods.
