Pandora is your own personalized internet radio station. Once you sign up, you start by telling Pandora about one artist that you like. It then uses data collected as part of the Music Genome Project to find other music you might like. It then begins playing music. As each song comes up you have the option to give it a thumbs up or thumbs down. Pandora then uses this feedback to refine your playlist. Even better, Pandora now supports several mobile phones. You can see if they support yours at here.
