Make Your Own Radio Station

I've been turned on to a wonderful music site, www.pandora.com, that allows users to create their own internet radio stations based on the types of music they enjoy. The company has a team of 30 musician-analysts who work out a few hundred musical attributes of every song in their library, currently around 300,000 songs. For starters, you input an artist or song you like, and the site streams songs with similar musical attributes. You can provide feedback if you particularly like or dislike a song, and the site will adjust the programming accordingly. By selecting music based on the musical attributes rather than, say, "oldies" or "top 40," they manage to provide an interesting mix of songs and artists you might otherwise not have given a second thought to. I probably would not have considered anything by R.E.M., but it came up on my station based on The Monkees (subtle vocal harmony, mild rhythmic syncopation, male vocalist, and major key tonality), and I was surprised at how much I enjoyed it. I have another station based on "Dueling Banjos." Doesn't everyone occasionally like good bluegrass instrumentation, heavy on the pickin'?
