So today it is Jay-Z with the satanic messages, eh?
When I was in middle school my parents had enrolled me in a very strict Southern Baptist private school - all the fire and brimstone you could desire. We had daily chapel services where the pastor preached on the evils of rock and roll and the satanic backmasking contained therein. Back then he was still harping on Led Zepplin, Ozzy, Black Sabbath, and The Beatles, even though it was the early 80s. We had book and record burnings there too, it was pretty scary stuff.
Of course the only effect it had on me was to make me go out and buy all of the above mentioned artists to see what the big deal was all about.
Any psychological problems I may have I attribute to attending that school for two years, lol.
