I've been trying to decide whether or not to post this in the beginning singers board because I'm not new necessarily, I've been an Utaite (not a youtaite) for about a year now, but I feel as though it is a "newbie" question. If it's in the wrong place my apologies.
Anyway, I was wondering about the legal issue of singing official songs from things like anime and games and pro artists. I've only ever sang vocaloid songs so I've never came across this roadblock, but I would like to cover one of RADWIMPS songs from Kimi No Na Wa and I'm not sure if I can legally. Did Utaite like Sou and After the Rain get permission before they covered songs from the film? Or did they just do it? Would I have to get permission from the band to cover their music?
TL;DR Can I cover songs from pro artists and official media without asking permission? Thank you~
