You're a stereotype; the word "metal" can really mean anything from Black Sabbath and Metallica to Slayer or Dimmu Borgir. Black Sabbath? "Screaming people"? Noisy"?
Since you're a fan of downloading music, try and get yourself Nocturnal Rites' song called "Awakening". It's classed as metal; so ask yourself when listening to that song where the "voilence" and "screaming" is.
