Tim Westergren:
«Something unique about Pandora is that all music, once analyzed by our musicologists and entered into our database, wins and loses audience in the purest of democratic processes. If listeners vote “thumbs up” a song and artist are electronically added to more station playlists, the exposure is greater, and more people can offer opinions about that music. If listeners consistently vote “thumbs down” then the song is performed and heard less. Not even my musical tastes or the CEO’s favorites can modify the purity of how our musical taxonomy determines all Pandora radio performances»
