> Pop has become a massive historical experiment in perceptual psychology. The most popular bands can literally fill a stadium - something common practice music has never done. > While that doesn't mean pop is better in some absolute sense, it does suggest it's doing something right for many listeners. Not Saying you're necessarily wrong, but you can't say just that without pondering that question : is it due to discoveries in music composition, or is it due to efficiently applying marketing to it ? I don't know if it's the same everywhere in the world, but here in france, if you turn on the radio and zap through channels, you will hear the same song up to 10 times a day. Then you turn on TV on night and see those same groups as guests on TV show. Then you read in local newspaper than they will play in your town. I can see how it could produce the effect you describe.
