Metal-Rules.com's "Top 100 Heavy Metal Albums"

This list only has a very narrow style to it. And please! 1984 by Van Halen?! That’s not metal – it’s like, top 40, cutesy stuff. A lot of this is good, but there’s not enough variation – how about some grindcore? black metal? industrial metal, etc?
Most influential – in a list of 100, and there’s not a Mayhem album?
