"2012 has been a strange year for content creators — authors, producers, musicians. It was a year when the very idea of physical ownership of a book or CD or even a song file became almost passe."

"It was also the year in which music-streaming services like Spotify and Pandora launched major efforts to convince people to pay for something they didn't own. But it's been slow going."

"Music-streaming services have been trying to win over two types of customers: a younger generation that doesn't buy at all and an older generation that still likes owning physical albums."
