That whole list sucks, unfortunately. And since it represents the reality of Metal's present status, to the world this list IS Metal circa 2008. What does this tell us about ourselves?
A scan over the list would reveal the values of the contemporary semi-commercial Metal musician. His instincts drive him to make gay videos (and by "gay" i mean anything other than a concert bootleg). Album by album, he must sacrifice a portion of his original metal soul, to be replaced with more "commercial rock" appeal, grasping for his wider, more generalized audience. He is obsessed by image, and will do anything up to & including prostitution to fulfill his bizarre hero image of what a Metal star "should" be. His primary goal is to appear Extreme, but since his psyche is absorbed by the creeping middle-class self-obsessed materialism, he must grasp at whatever straws he can find on the street towards his supposedly extreme statement of self. He gets tattoos. He does any drugs he can find because he's usually paid in drugs. He wants to be a crusader for something, but lacking a cohesive philosophy and political worldview for himself (beyond his desires for instant satisfaction), the best he can come up with is to emulate a sexually repressed hobo junky.
The artist is free to do this, because the wonders of digital recording technology enable him to grow mentally incompetent over the years of plenty, but still leave the studio with some sort of studio-quality music each time. Modern metal often has a Nintendo, 8-bit feel to it sometimes; it's quite possible that this may be due to the interlocking nature of digital audio and multimedia software.
