A leading music recommendation and Internet radio service from Pandora Media, Inc. (www.pandora.com). Pandora lets users create their own radio stations by selecting a favorite artist and voting thumbs up or down on each song that is delivered. The more users vote their preference, the more Pandora fine tunes subsequent recommendations for that station. Songs can be heard on the computer from the Pandora Web site or from Blackberry, iPhone or Windows Mobile smartphones. User selections made on the Web appear on the phones and vice versa.

The Music Genome Project
The heart of Pandora is the Music Genome Project that was started in 2000 by Will Glaser, Jon Kraft and Tim Westergren. It is a musicological study analyzing 400 attributes of a song, including melody, harmony, the singer's voice and instruments. Pandora uses its history of billions of thumbs up and down in combination with the music DNA to recommend songs. It should be noted that the "music DNA" has no relationship to the acoustic fingerprints used to identify a song (see acoustic fingerprint). See Last.fm, music recommendation service and music search.
