At the moment mostly either alternative country (16 Horsepower and Calexico, mostly), and jived-up Eastern-European folk music (Goran Bregovic, Fanfare Ciocarlia, Boban Markovic Orkestar, etc.).
But I like a lot of other stuff as well, depending on my mood - from 1950s jazz (Chet Baker, Miles Davis), to Afro-Cuban music, to 1970s funk (I love Curtis Mayfield), to Brasilian music, to baroque orchestral music, to some mellow electronic dance stuff (Massive Attack, Rockers HiFi), to 1980s/early '90s alternative/punk type music (which I grew up with - Pixies, Hüsker Dü, Sonic Youth, Replacements, Green on Red, Gun Club, Nick Cave, Lemonheads, Dinosaur J. etc.).
The only things I can't stand at all are opera (those singers make my teeth want to fall out, and I have a thorough dislike for pathos), top 40s mainstream sh*t (Britney Spears et al.), and 1970s prog rock dinosaurs (hey, I was a punk rocker once...).
