Some of the most stirring and thought provoking music of the 70s and 80s were Rap or Rap inspired listen to Grandmaster Flash -White Lines Public Enemy etc. and tell me that it's trash. As it developed from Subterreanean Homesick Blues (supposedly) then you will agree the same for songs of Woody Guthrie and the enigmatic Mr.Z I suppose? In the 1940s people were ridiculing Jazz, in the 50s it was Rock and Roll, and so on, and so on. These people were afraid of change and tried to maintain the status quo. But we all know now that there is something positive to be gained from every new cultural development and ridicule and negativity toward new ideas amounts to oppression and censorship and where did those evils ever get us? If you're going to criticize at least have the decency to do some research first.
