I agree with number one I'm surprised that you didn't include Robert Plant.
I would say Robert Plant (Zeppelin) is more hard rock rather than metal such as Iron Maiden and Judas Priest...even though I think they were "metal" back in the 70's...
Also go away. I don't think you're part of AMMO. :P
NEVERRR... *Goes away*
Aww and here I was hoping for some resistance...
