Ironically, much of the things PJW is going to bring up would've existed for every pop culture movement at some point in time. In the 80s there were people who thought that rock and pop all sounded the same and that 20s jazz gave a much better message. In the 90s there were people that thought that the hip-hop movement was promoting violence and youth to drop out of school, and 70s folk songs were better. We now have people who say this pop culture movement sucks and everything about it sucks, and that the 90s was 'much better' or some dumbstuff.
the trends of popular culture stay the same every movement. the only thing that changes is the audience's tastes.
