Launched on August 29, 2005, Pandora's online music service (www.pandora.com) is based on the Music Genome Project, which began in 2000 and is the most thorough analysis of popular music ever undertaken. Each song in this massive collection, which covers Pop, Rock, Jazz, Electronica, Hip Hop, Country, Blues, R&B, and Latin, is analyzed by a trained musician along 400 distinct musical attributes (such as melody, harmony, rhythm, etc.) to capture its unique musical identity. Music lovers need only enter the name of their favorite song or artist and Pandora does the rest ? creating a tailored stream of songs that share key musical characteristics — launching a personalized listening experience, full of new discovery across the genome. Listeners can create up to 100 of these online radio stations, refine them by providing feedback and even email them to friends.
