"People want to own their music," Steve Jobs said. "The subscription model has failed so far ... never say never, but customers don't seem to be interested in it," he told an interviewer in 2007. Were he alive today, Jobs might be rethinking that stance: Customers are interested; some 20 million paid for music subscriptions last year. Meanwhile, an estimated 80 million tap into "freemium" streaming services such as Pandora and Slacker. A decade after the iTunes Store opened and changed the way people buy music (it will pass the 100 billion downloads mark this year), another technological shift is transforming listening habits -- and in many cases causing music fans to pare down their dependence on Apple.
