as a metalhead, i can tell you that metal is good. Helmet is metal (loosely) and i think most of you would enjoy it( Jeph appears to).
Also, try Slayers Cosmic Sea, for a wierd yet oddly enjoyable metal song.
also, megadeath, metallica, slayer, helmet, Iron Maden, BlackSabbeth,(pretty much metal), Dokken, Venom, Cacophony, Tesla, Helloween, Accept, Grim Reaper, Judas Priest, Ac/Dc, Helix, Def Leppard, Exodus, King Diamond, Pantera, Hamlet, (Motley Crue, Guns and Roses, Classic rock now) Sepultura, Gamma ray.
Pretty much my whole collection there...
phew!
