The elitism of the more intolerant metalheads is amusing to this old codger (who remembers when the first Sabbath LP came out).
As someone who works in the music industry I find most metal to be pretty bad but the stuff I like I like a lot (stuff like Coalesce which adepts tell me is "math metal"or the Locust who are pretty undefinable so I chose "other" in the poll). Silly lyrics don't help (good thing I can't hear most of them intelligably). There is no genre of music that seems to attract fewer female fans nor is there a worse genre of music when it comes to tipping bartenders (even punk rockers and shrub folkies tip better). I have never heard of a gay metal band ever nor have I heard of a socialist/Marxist metal band (anybody know of any?). The thing that should worry the "true" metalheads is that it sure seems that metal has painted itself into a corner stylistically; you can only scream (or growl) so loud and put so many de-tuned strings on you guitar before it simply becomes noise. The only place left to go is backwards it seems. As a lover of literally every style of music I consider metal to be electric chamber music; tightly arranged with minimal improvisations (wanky solos mostly). Wish there was more metal out there I liked but too much of it is reactionary teen death fantasy goth crapola. Not for nothing did the Cannibal Corpse box set come with a comic book.
I think that all goes back to when people were trying to make a distinction between "metal" and "hard rock" and it just kept going from there with the addition of "hair metal," "punk" and "progressive" styles of music. What people tend to forget is that all of these things still fall under the main heading of "metal" (yes even the majority of "hard rock" bands still fall under that when talking about bands like AC/DC, early Aerosmith, Def Leppard, etc.) because of bands like Black Sabbath, Deep Purple, etc. all becoming big around the same time (late 60s/early 70s... before there was category called "metal.")
