I came into this thread all kinds of ready to rail against stereotypes and hate all over metal, but I really cant. I don't listen to metal as a rule....anymore. But, I used to.
I still carry a soft spot for TOOL and their meandering, progressive stylings, and I have a hard time hating anything performed by the mostly fictional (and utterly entertaining) Dethklok, but other than that, metal doesn't interest me anymore.
If my predilection for gaming has had any effect on my musical tastes, it's certainly affected my desires for music that's largely instrumental. For me, this mostly manifests in music from the electronic side of the spectrum, but I wonder if it would be little stretch for this to manifest into a greater appreciation of metal by others.
My experience with the music leads me to conclude that it is, in most respects, largely instrumental. While there are often...er, "lyrics" as well, they often are so heavily blended into the general noisescape as to simply be another part of the overall sound.
Now, I'm just randomly theorizing and not really driving toward any ultimate point here....er, never really had a point to drive whatever I said above home, but eh...I"m just going to stop writing here and push this pretty little button under the text box.....now.
