Sony Music Entertainment was the one who blocked it, and they seem to be the label that has rights over the song, so you are likely correct.
Edit: As expected, Kanauru once again proves his worth.
I just love how this fucking negro went from shitposter to 3d lead animator of holoEN. He also did something for flare I saw, so he's most likely in bed with the JP girls now. I wish him the best and it just goes to show how far you can get if you aren't a colossal femboy. Can you imagine having your foot down on holoEN and sperging over something quite stupid and lose all of it? I'm sure there aren't people like that out there
