Okay.. on a more serious note.. I'm a little eclectic. Classically (although not strictly limited to "Classical" period music), I like Mozart, Beethoven, Tchaikosvky, Satie... anything really. I'll listen to some opera (I really love "Carmen".. like.. seriously...) Um, then there's some Medieval stuff before that that's ok... I really quite like this french singer at the moment, Camille, and St Germain is alright as well. Um.. artists/bands.. I listen to some Incubus, Billy Joel, a little of the earlier Lauren Hill stuff, I really like Robin thicke and The Idea of North, The Butterfly effect and Metallica are okay... and some Trapazoid (who pretty much no one has heard of... for those that want to know, just look up "Matt Trapnell").
As far as styles go, I will listen to anything -- although country music is left for when I'm really desperate for some form of sound other than my own thoughts... and even then it's a very difficult decision. I do not like country music. Basically, what you see outlined here is my musical taste in it's barest, most skeletal detail. I could go on for days pretty much, so I thought I'd spare you all.
EDIT: OMG I forgot to mention Jazz.. Right now I'm really into Kurt Elling.. but I really like any jazz (Herbie Hancock's compositions are really hot...) and fusion-jazz, as well as fusion-classical music (like hip-hop remixed Tchaikovksy) are really cool too.
