Music Discovery Service

"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 takes your input (artists, songs) and feedback ("I like this", "I don't like this") and uses the Music Genome Project to create stations that play songs that are musically similar to what you've told them.

Released earlier this summer, Pandora Backstage is a searchable database with information on various artists and their music.

Another more inclusive searchable music database is AllMusic.com.
