The appeal is to their desires. And, original sin being what it is, some of the deepest and most lucrative desires are sinful. Today's popular music manufactured for the youth market generally scorns authority, lauds illicit sex, and lifts up pleasure as the only good. In many cases now, it goes even further, wallowing in overt evil. Gangster rap, now a favorite of white suburban teenagers, glamorizes rape, drugs, and murdering police officers.
Death metal spins dark fantasies of vampirism, sadistic sex, and demon worship.
Marilyn Manson sings songs about kids murdering parents. Obviously, few of the fans of Marilyn Manson actually carry out what they are listening to. Most listeners are content to enjoy such degradations in the privacy of their imaginations. Even though they never act them out, the spiritual impact remains. A very few are not content with the vicarious experience of evil, but want to play it out in the real world.
