Pandora Music Discovery is Now Free (ads-supported)

Pandora is a music discovery service and player which streams your favorite music and suggests similar songs and artists.

Pandora is based on the so called Music Genome Projects. The project started 5 years ago and includes 30 musicians who have analyzed 400 attributes of songs, like melody, rhythm and vocals. Users choose an artist or song to get started, and create a “channel” to stream music, then Pandora suggests similar songs. One user can have up to 100 channels.
