Pandora has no concept of genre, user connections or ratings. It doesn't care what other people who like Gomez also like. When you create a radio station on Pandora, it uses a pretty radical approach to delivering your personalized selections: Having analyzed the musical structures present in the songs you like, it plays other songs that possess similar musical traits

Pandora relies on a Music Genome that consists of 400 musical attributes covering the qualities of melody, harmony, rhythm, form, composition and lyrics. It's a project that began in January 2000 and took 30 experts in music theory five years to complete. The Genome is based on an intricate analysis by actual humans (about 20 to 30 minutes per four-minute song) of the music of 10,000 artists from the past 100 years. The analysis of new music continues every day since Pandora's online launch in August 2005. As of May 2006, the Genome's music library contains 400,000 analyzed songs from 20,000 contemporary artists. You won't find Latin or classical yet: Pandora is in the process of developing a specialized Latin music Genome and is still deep in thought about how to approach the world of classical composition.
