This has probably been asked before, but I am curious about the musical tastes of all the rest of you, having noted very similar tastes in the "Ask YC: Books" thread.
I'll start us off:
Mashups:

Also all manner of classical: Bach, Mozart, Strauss, Beethoven, Debussy
And last but not least, some excellent indie radio: http://www.bagelradio.com/blog/index.html

Choose "Rain MP3 Download". Twelve bucks gets you an hour of rain without any background noise at all.
Note that you'll need to play with Winamp's equalizer a bit to make it sound great through headphones. The Full Bass preset is perfect.
