Pandora has been building a buzz in indie music circles lately:

Pandora is a music discovery service designed to help you find and enjoy music that you'll love. It's powered by the Music Genome Project, the most comprehensive analysis of music ever undertaken. Just tell us one of your favorite songs or artists and we'll launch a streaming station to explore that part of the music universe.

Pandora tries to automatically match songs with similar sonic qualities, creating a streaming playlist of songs that appeals to the listener's personal tastes. Here's how to submit your own music to Pandora.
