The economics of the recording industry are changing. “The success of iTunes has made clear to the music industry an uncomfortable truth: many people want to buy single tracks, not albums. Apple’s data show that its customers bought 12 singles for every one album at iTunes. That compares with 0.02 singles per album in American stores, according to research by Sanford Bernstein. The best artists may tempt people to buy a whole album. But the industry can no longer rely on getting the price of an album as a reward for backing a band.”
