Check out Pandora

[Flint]

It's more than just a playlist randomizer; it's based on the music genome project:

...an effort founded by Will Glaser, Jon Kraft, and Tim Westergren to "capture the essence of music at the fundamental level" using almost 400 attributes to describe songs and a complex mathematical algorithm to organize them.

Today I am using the browser-independent Pandora application . One (minor) drawback: although you can view your stations, it doesn't highlight the station that the song currently being played is on. I use a quickmix of 11 distinct stations (so that I can cultivate each one and toggle by genre):

• 2112: I/II/III
• Classic Psychedelic
• New Age Electronic
• Avant Garde/Free Jazz
• Drum'n'Bass
• Motown Custom
• Smooth Jazz
• Bebop/Combo Jazz
• Rock/Pop Setups
• Instrumental Hip Hop
• Electronica Custom

Once again, I have to mention that the 192Kbps sound quality makes a huge difference. The enriched experience is well worth approximately 10 cents a day, as is the expanded five-hour timeout window. I wish I would have done this a long time ago.
