I don't think the analogue with movies was a good one. The time investment of several hours involved in going to see a movie is more than the actual money cost for most people. There are many movies that wouldn't be worth seeing if they paid you. Music has this as less of a factor because the time investment is so much less. Usually when you are going to buy a song you have already heard it.
