Not really relevant to the current topic of Pandora's relationship to music, but for those interested in the historical problem with music (and the music industry), I strongly recommend reading "The Problem With Music" by Steve Albini (From The Baffler, No. 5, 1993)[1]. This was my first introduction to The Baffler, and led me to start reading their publications regularly. I don't always agree with the author's point of view, but almost always find the content stimulating.
