I don't really believe that what's popular in music is simply a reflection of what people want. It's more like what someone's marginally accurate model of the public wants. Same with movies. Studios experiment and when they find something that is commercially successful, they make more of it. A lot of good stuff doesn't get made or promoted because they think it wouldn't have the broad appeal to be commercially successful. A lot of what's popular just got that way through promotion, not because of its overwhelming merit.
