Joe turned me on to it - it's the result of 'The Music Genome Project' - you can create different 'stations' according to a song or band you like - in short, it's legal free music - I've been listening to the Be Good Tanyas station for days (Angie, you will love this one) - Pandora will randomly play music stylistically related to the song/band you pick - a great way to hear new music you'll like - I've found that I love Sean Hayes (listening to him now) - here's Pandora's write up:
"On January 6, 2000 a group of musicians and music-loving technologists came together with the idea of creating the most comprehensive analysis of music ever. Together we set out to capture the essence of music at the most fundamental level. We ended up assembling literally hundreds of musical attributes or "genes" into a very large Music Genome. Taken together these genes capture the unique and magical musical identity of a song - everything from melody, harmony and rhythm, to instrumentation, orchestration, arrangement, lyrics, and of course the rich world of singing and vocal harmony. It's not about what a band looks like, or what genre they supposedly belong to, or about who buys their records - it's about what each individual song sounds like."
