The lifestyle ruined their skills and talents mentally and physically. Society and civilization followed them. Then people thought disco and punk were the answer and they were wrong (for the most part but not entirely as there were good songs there). Then the public started to embrace what they thought was safe with so called country music while others became more extreme with rap. Then MTV was bought by Viacom in 1991 and things went downhill from there. Plus there was the issue of A.I.D.S. on top of everything from the early 1980's. Then on top of all of that people (including the recording artists themselves) not only do not understand or value freedom and capitalism but had no idea that they were in a business so when everything was stolen off of the internet they were out of the job.
It was said that live music was the future but that's equivalent to saying bread is the new sandwich as if that is something new. It means you go without and the rest of you are wondering what in the hell happened to all of what made sandwiches sandwiches like a bunch of baboon idiots. Then when everyone were lost and confused they turned to David Geffen's (who continues to hide on his city sized yacht all over Earth) monster Obama and thought it was a good idea to surrender our wars, their freedom, their children's, their communities, everything everywhere for a piece of candy. Hell, they didn't even get that. But that's all o.k. because they will do it again. Just pay attention to your beer and football.
