When Alyssa Rosenberg claims that the motion is toward paying for specific items, she seems years out of date. The visible motion is in the other direction. People are stopping buying individual recordings and are instead using services like Spotify, where they are paying for access to a large library of music at a fixed price. They can listen to Muppets today and Ben Folds tomorrow, and if they never want to hear George Clinton, they don't have to, but he's still available as part of the deal. In movies, people are buying far fewer individual recorded films, but (except for sizable blips caused by sudden pricing changes) they have been swarming to services like Netflix, which offer them one-price access to huge libraries.
