I'd be happy to run this too...
But also, i've been talking with my friends, and we all agree that Iron Maiden are closer to Power Metal than HEAVY METAL, or they could go under Classic Metal.
Also where is Nu-Metal?? Godsmack, Slipknot, Disturbed, KoRn, Stone Sour,
Where's Motley Crue, Quiet Riot and Def Leppard?
Also i don't see Rammstein, Skid Row, Saxon, BLack Label Society, Machinehead, Lamb Of God, Chidren Of Bodom *as stated above, System Of A Down, Trivium, Bullet For My Valentine, Tool, WASP, Yngwie Malmsteen, Soil, Cradle Of Filth???
You may even want to include some others that are considered Metal:
-Evanescence (Gothic Metal)
-All That Remains
-Nine Inch Nails
-A Perfect Circle
Now surely there must be some you're missing there..
