Then you're sure as hell lending a lot of credence to them.
Not at all. I'll think you'll find it's more a case of "gone were the days of self indulgent guitarists making up for crappy songwriting". I love good shredding as much as anyone else but that movement in music forced people to concentrate more on whether the actual songs were any good, rather than just impressing people with technical virtuosity. As a result we now have a happy medium where a lot of bands are making good tunes that still remain technical.
The words 'Machine Head' spring to mind. They exploded at around the same time. Why? Because they managed to make a record that was heavy as fuck, had a bunch of solid tuines, and still kept the solos but with very little wank. It's the wank, and people waking up to the fact that it was wank that killed wanky metal.
A lot of people find it hard to beleive that cock-rock type metal "killed itself" with it's own giant pelvic thrust. And no type of music dies anyway. I personally don't call something jumping outside of the eye of the mainstream dying. I call it a new lease on life if anything.
Look...this whole fucking thread is bullshit. Just look at the title "who killed metal" (and the fact that myhatbroke, the OP of this thread, is a bit of a muppet, and was a lot more of one back when he started this stupid thread) and then go for a walk down the high street. What made anyone think it was dead? I see more metallers than ever walking around these days. The question should be "who made metal fashionable again?".
