yeah I don't agree with all of it either lol...
however
in response to GreatDeciever as well, I don't entirely denounce slipknot, and manson just because they are newer. I don't like korn tho.
and twisted sister, and skid row are questionable as being good to begin with haha... motley crue, and even guns n' roses shouldn't be in the genre, but they still rawk.
the order in which the songs rank is totally off, I agree as far as iron man goes, it's great, but overrated. but in that sense, metalica is overrated as well, and I still listen to the old school stuff of theirs.
I did say that it's not 100% but in my opinion, Pantera, Fear Factory, Slayer, Motorhead, Machinehead, Anthrax, White/Rob Zombie, Metalica, Rage, Judas Priest, Sabbath, ACDC, Alice in Chains, Sepultura, Megadeth, and Iron Maiden all have at least 1 MUST HAVE album, if not a few.
p.s. does anyone in here like American Head Charge?
