• This song is a celebration of heavy metal music. Soulfly frontman Max Cavalera told Metal Wani about the track. "I was playing around with the song, playing it for people, to see what kind of reaction it gets," he said. "And almost everybody, the reaction was, like, 'This is so crazy. I can't wait 'till you guys play this live.' It's got this kind of New York hardcore chant that we do in the chorus — like, gang vocals. It's really, really fun, and everybody gets to sing together. That's why I was thinking that it's gonna become an anthem — the chorus, all the fans are gonna sing it together, and it's saying something. 'Cause, 'we sold our souls to metal,' I think every metalhead feels like that — that we did kind of a pact and we sold our souls for this music that we love so much. So it's something that I think [they'll] sing that with some kind of pride. I think it's gonna happen when that song comes out, at least."
  
  "And then it ends [in a] very Pink Floyd [-like way], which is really strange," Cavalera continued; "I don't know why we did that. I still don't know if it was the right thing, but it came out like that. Marc [Rizzo] just did some really crazy guitars at the end of it that is just, like… It goes from total metal into crazy Pink Floyd, but it works. I mean, it's really wild. And we like wild stuff. I always was drawn to weird, weird stuff, and that's definitely weird, in a good way."
