If I remember correctly (I think it was the Peters brothers?); the argument went that the rock beat was intrinsically evil, got your heart going too fast and made you want to fornicate. Everything was condemned, including Petra, Amy Grant, and especially Stryper. Only church music and NO DANCING!
I have a book at home, by someone other than Peters, but it's along the same lines. It would be funny, except the guy says offensive things like "Jimmy Page's four year old dying in a car accident was punishment from God". Why God couldn't target Page himself rather than the child isn't explained. (In fact the NT story about the blind son I think abrogates any rationale for this type of OT behavior by God).
But anyway, it was reading crap like this that led me to repeatedly sell and buy back some of my favorite albums . I'm sure I went through at least four copies of Stained Class over this sort of ridiculous agonizing. I want to be clear here that I'm not making fun of matters of personal concience. If a person feels that a secular album is offensive personally then I can respect them not listening to it. Nothing wrong with that. And of course children need to be protected from lots of stuff, theological and otherwise (crap T.V). However as a young adult my tastes were being dictated by the concience of others, not my own concience. As an adult, the idea that I can read the Bible, theology, and religious history for hours every day (which I do); and then be dragged down by some idiot (a brilliant musician, but an idiot) like Ozzy is just silly. If I'm gonna be dragged down, it's gonna be by Nietzsche or Richard Dawkins or somebody good at talking forward, not some stoner who happens to be good at writing songs or singing backward.
Here ends the sermon.
