Ask YC: What music do you listen to when programming?

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: http://bootiesf.com http://djearworm.com http://partyben.com

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
