Iron Maiden: Iron Maiden (1980) Killers (1981) The Number of the Beast (1982) Piece of Mind (1983) Powerslave (1984) Somewhere in Time (1986) Seventh Son of a Seventh Son (1988) ^ Those are the essentials for studio albums (Optional After Having those) The X Factor (1995) Brave New World (2000) Dance of Death (2003) A Matter of Life and Death (2006) As far as individual songs go, get the live version of "Fear of the Dark", from Iron Maiden's A Real Live One / A Real Live Dead One. Edit: System of a Down's lyrics don't make me laugh, I'm sorry. A couple of times I've laughed during some metal songs, would be S.O.D.'s Speak English or Die. Lamb of God, doesn't interest me. You want heavy? I'm not the biggest Deicide fan, however their first two albums alone, crushes Lamb of God's discography.
