Heavy metal suicide (1964-89)

Lawsuits were made against heavy metal groups of Ozzy Osbourne and Judas Priest claiming that their lyrics encouraged and caused the suicides. Reference: http://www.reversespeech.com/judas.htm
Note that another viewpoint is that Billy Joel had two topics here: Heavy Metal, where heavy metal rock comes on the music scene, and Suicide, where the suicide rate among young people seemed to be rising.
