I prefer complexity and authenticity. Pop music, for the most part, sounds like plastic to me. Bland, soulless, and manufactured. Of course you can see this in any genre, but pop is 99% assembly line nonsense - half the time the lyrics aren't even cohesive, but rather random phrases jumbled together to evoke some sort of base response (see N'Sync, uuuugh, just random collections of romantic sounding phrases to a beat). Country music is another especially big culprit, as well as rap-rock and quite a bit of "gangsta" rap (quotes because half these guys talk completely out of their ass, some of them are cool).
Other than that, man, I'll listen to just about anything. Lately it's been Celtic punk (Dropkick Murphys, Flogging Molly, Flatfoot 56...), flamenco, a little bit of epic metal (Iced Earth, Demons & Wizards), some classical symphony and piano, a lot of classic rock (Zepplin, the Doors, Pink Floyd especially), and the grunge and rock-alternative I grew up on (Smashing Pumpkins, Nirvana, etc. late 80s-early 90s). I also tend to like industrial electronica (Kidney Thieves is my favorite by far, Chiasm is good), prog rock (Tool!). A little bit of rap if it has the sense to be intelligent and socially insightful rather than self-destructive and repetitive. And I don't know where you'd stick SoaD, but they have some of the richest and most complex lyrics I've ever heard in music.
I'm a married heterosexual male of northern european descent. So. No I don't think there's much to gender or sexual preference, but I guess you can probably squeeze me into a profile if you like.
