I must admit I've grown a taste for politically charged music, and 60's tunes... right now I'm hot on Bob Dylan.
Later I might throw on some Rage Against the Machine.. maybe some Darude (who IMHO makes some of the most interesting dance music right now - aside Faithless of course who are hard to beat in that department)
Man I love my rhythmbox.... playing cool tunes 24/7 (well except when the gf is sleeping - in which case I have to dig up my headphones... and music just doesn't sound the same in headphones.
btw. Rhythmbox CVS has a cool db backend - cataloging 15 gbs of oggs take no time now... sadly the internet radio is defunct right now.
