extract: As for aural pleasure: if you've turned on a hit radio station in the past 15 years, you know exactly what music porn is (I don't mean Barry White). Record company executives use focus groups to find what song elements give a tune mass appeal, and set up what has become an assembly line that begins with a good-looking teenage singer and ends with a song you can't get out of your head for a month. They also take advantage of a concept familiar to psychologists: the more exposure we have to a certain song, the more we will like it -- regardless of its quality. It's a natural human tendency to confuse catchiness with fondness. The songs are composed so that they are tolerable enough for most people to keep their radios on the station, and catchy enough that the listeners will repeat them afterwards. The result is a flood of manufactured music -- void of emotion and authenticity -- that spreads like a contagion.
