I've noticed that people always hate on country music in these types of lists. Is this simply a manifestation of a need to distance oneself from the culture of the Southern U.S. States, from a certain ideal present elsewhere, from over-exposure? I've always wondered.
Anyway, I'm into:
Modern: dubstep, d'n'b, house, metal (most kinds), rock, alt/electro, fusion, avant-garde, stuff that sounds like a Windows ME PC after being thrown out of a window.
Retro: new wave, synthpop, film scores, classic rock, music which makes you want to kill yourself.
