I know I've said that a billion times, but come on Bushiroad! Their song, "Say It," has 69 (nice) million views on Youtube! And their most viewed video has 88 million!
OH I JUST REALIZED ALSO!! WHAT ABOUT A KYARY PAMYU PAMYU COVER!!! What are you doing, Bushiroad, COME ON!!! KPP's "PONPONPON" has 162 million views. This might be because of licensing issues, though, since KPP is an idol.
But back to Yorushika. I'm not sure what band should cover their songs. I think Roselia would fit the overall themes in their music, but it also doesn't have a lot of high notes in the vocals, so Morfonica might also work. I asked this before but no one answered, what band do you think would fit their music (I'll put their two most viewed MVs here, and then their newest):
Off-topic, but what's your guys' favorite anime/visual-novel sountrack (as in background music)? Mine has to be the Clannad OST. That's just chef's kiss absolutely perfect. My two favorite tracks are "Nagisa" and "Ushio." I know it sounds kinda dumb to have your favorite tracks be named after two of the characters, but their beautiful tracks, okay! I'm not even sure if "Ushio" played in the anime, but it was the menu music for the visual-novel.
