This happens to be a pet peeve of mine and other than a few times when some groups did it on purpose (like ELO) is baloney as far as it bein' real messages from ol' scratch. If you Google the topic you'll find some research done by some Canadian psychologists and audio people debunking all this. I call it phonetic coincidence. Fer some reason the words "yes its" or something close to it sung or said forwards comes out backwards something that sounds kinda like "satan." Go figger. But I did a seminar on this 'cause I couldn't accept a buncha folks goin around saying the devil was influencing kids in songs like "Stairway" backwards no less. Stupid. Vokey and Read were the names of the scholars who actually looked into this and wrote some papers & articles on it. You'll get 'em if you Google their names. Anyways-if you have the equipment try recording "yes its" a few dozen times and then play it backwards. So any song with something in it that is "yes its" or close phonetically will come out "satan"--and what about homonyms? How ya sposed to be "influenced" without a context for the text? Eh? All started with "#9" from the Beatles White Album and Paul is dead thing. 'Course Pat Robertson would believe it-probably burned some Zepplin records back when. LOL.
