Bloods, Foo Fighters, and True: Actually I'm well aware that Metal is a  very broad genre. Emperor are very  different from Nightwish. Both are  Metal.  It's not at all about the heaviness of the  sound or harsh vocals, Power Metal  doesn't usually those as features. It's  not about playing fast, Doom Metal is  often very slow.  That still doesn't make Avenged  Sevenfold, Royal Blood or Foo Fighters  Metal. They are Rock.  You're correct that I'd say Sad But True  isn't a Metal song. It's on The Black  Album, and as stated earlier, that  album is not Metal.  What I'm getting from you isa  fundamental misunderstanding about  what Metal is. Which is strange, given  given band is Metal.
