The music you used in your example would incite someone who wished to emulate them, to take drugs, be moody, depressed and a party amimal. The lyrics HOTG used in his example would incite someone to be a criminal, a gunslinger and to hate. While someone might outgrow your example, kids arn't going to live long enough to outgrow being a hate filled criminal gunslinger.
I was going to post something very similar.
I have seen countless interviews with band members who made music like HOTD mentioned. Many made comments to the effect that they realized the more parents hated what they were producing, the more kids wanted it and thus, they made that kind of music. There is a stark contrast between the type of rebellion HOTD mentioend that most grow out of and the lifestyle that rap promotes. Not to mention much of the controversial hard rock/heavy metal as mentioned above was simply publicity stunts and marketing schemes. I am sure some rap is too, but it promotes a lifestyle rather than youthful rebellion.
What about punk music?
