Moral panic
From about the 1920s, different kinds of new music have been said to cause spiritual or otherwise moral corruption to younger generations. These were sometimes called "the devil's music". Blues recived this label; people believed it caused people to become violent, and to show other poor behavior. Jazz  also received such a label; traditionalists considered jazz to contribute to the breakdown of morality.  Blues and jazz were seen as "negro music" . Urban middle-class African Americans perceived jazz as "devil's music", and agreed with the beliefs that jazz's improvised rhythms and sounds were promoting promiscuity. In the mid 1980s, teenagers had killed themselves  after they had listened to music for some time; mostly metal. A label "Parental advisory:explicit lyrics" was introduced, but court cases to sue musicians because of the texts they used were unsuccessful. A group of parents were discontent, because the parental advisory sticker would not make a difference between music that was "offensive, satanic, sexual in nature [or] otherwise objectionable."
