Pandora is a unique internet radio experience – Pandora uses a system called the Music Genome project to analyze every song played on Pandora and uses the information gathered to create personalized radio stations for each user.

Pandora is proud of the fact that it chooses music for inclusion based solely on quality, and about half the music played on the station is from independent artists.

The submission requirements for Pandora can be found on their website.
