I don't think I have a favorite, as my musical-listening is really mood- and lyric-dependent. I guess I can't really listen to trance for hours and am not a huge fan of really aggro-metal or really aharmonious punk. I prefer Bach to Tchaikovsky, Guy Davis to Miles Davis, old Madonna to new, Jay-Z to Nas (but I'll listen to any of the above) and anything my friends play me to whatever the algorithm on the radio tells the DJ to throw up next.
