Yes; this. During that era, there were school conferences about the horrors of listening to heavy metal music. Parents were given lists of things to look for, and it wasn't unusual for kids to have their rooms searched for things like black clothing, stuff related to Dungeons and Dragons, tarot cards and Ouija boards...all signs of a baby sacrificing, mass murdering, virgin killing, blood drinking Satan worshipper cleverly disguised as an ordinary child.
Some kids started believing they really were "possessed" or "evil" because they simply couldn't deny loving Iron Maiden and Black Sabbath -and of course, those band names played right into the fears. So, of course, they lived down to the expectations, and proceeded to find trouble simply because they believed it was their destiny. Others saw making claims of terrible deeds as a way of scoring points with these mysterious, unnamed rulers of the world. It wasn't entirely unusual for a kid to come to school claiming he had burnt down a building or cut the throat of a virgin -bald lies that gained all kinds of attention and created a spooky reputation no one else wanted to challenge.
Parents who had never actually listened to Twisted Sister, and had no clue what they sounded like, were full of lore about "backward masking" and "hypnotic subliminal messages". Gospel preachers on television never ran out of things to say about the way Satan had infiltrated the school and was forever ruining the eternal souls of those who listened to lyrics rife with sex and violence...even if it wasn't nearly as raunchy as the stuff of prime time TV.
