At my congregation back in the 80's-anything by Michael Jackson was banned because he DA'd himself. It was mentioned that it would be like inviting him into your home to visit if you played his records/cassettes. And I LOVED me some Michael Jackson-still do.
These movies/songs are banned if you are a JW
I had my Harry Potter books thrown out back in 1999 when Harry Potter started getting popular. I also heard back when I was a kid that Britney spears and Back street boys were banned.
