Eu nunca vou conseguir dizer melhor....
"Heavy is about being pissed off and being a warlord and laying down... like, just like, someone like, that was a battle, just if they had an axe they just chop some dude in the head, and it landed... And you got a riff that plays the same way that way, that's heavy!"
o resto, bem o resto é o resto por alguma razão...
