Judas Priest
Their parents thought they heard "do it" being sung in the band's song "Better By You, Better Than Me" from Stained Class (actually a cover of a Spooky Tooth song). They said the words in the song made them shoot themselves. The trial was dismissed in August 1990 when Rob Halford played a clip from their song called Exciter in reverse, so it sounded like Halford was singing "I asked her for a peppermint, I asked her to get one" (the actual words were "Stand by for exciter, salvation is his task"). He did this to show how any reverse messages in their songs suggesting suicide were accidental.
