When I was a kid one Sunday the sermon at church was about Marilyn Manson. He said his music was about all these terrible things, he might be a Satanist, he looked like a woman, and he supposedly was really popular among kids and teenagers.
I had never heard of him at that point and had no idea who he was, but my interest was piqued. I had to see how weird this dude was. As soon as we got home after church I got on Napster and downloaded the entire Mechanical Animals album, which had just been released. I ended up not even liking it and deleted the songs so I didn't get in trouble, but I would not even have known what it was if it wasn't for our preacher.
I'm not sure why people don't understand this. If you go to a group of people, especially kids who are much more naturally curious than adults, and say "This is bad, don't don't read it" it makes it way more likely they'll read it.
