I think Metal is one of the most untapped music genres for videos. (Along with real early 70s punk.) There's so much good metal out there that has yet to be used. People usually end up using some corny ass metal like Iron Maiden. Also sorry Carbonite, Judas Priest has some great songs, but I think Carroll's song is a perfect example of the type of metal that shouldn't be used.
I was super fucking impressed with Slash using Holocaust for his Black And Blue section. Pretty much made me instantly like him for life.
Diamond Head's Am I Evil always needed to be used, but I don't really think it fit Vincent Alverez's section, or Ty's blockbuster style editing.
But yeah, there's tons of good more obscure metal out there that would be so good for sections.
And then of course there's this. Best music choices ever.
