I like Led Zepplin a lot but listen to this segment of Stairway to Heaven backwards. It's got satanic messages, no seriously! Look at the page, pretty cool find.

 

ive heard that stairway backwards so many times LOL. its hilarious how people have really tried to listen to it backwards and try to decipher a message. actually there were a couple more led zeppelin songs with "messages" lol.
and that "Paul Is Dead" theory is hilarious also. supposedly paul died and was replaced by someone who looked like him and got some surgery to look like him more. supposedly there are hints like the one given in that site, and they also use the fact that Paul is walking without shoes in the Abbey Road cover, just like dead people are burried without shoes, and a cover of an album where paul is in a box, as if it was a coffin. LOL
the pink floyd message was done purposely lol.
i think its better when bands make a backwards message on purpose, like this one by Spastik Ink (funny stuff, especially the part when he says "I'm talking like this because it sounds really scary backwards" LMAO
Multi-Masking (heard backwards)

 

Paul Is Dead !!! lol
Paul Is Dead

 

If you play Barry Manilow's "Mandy" backwards it says "Tom Daschle is the debil!!"

/serious.

/ok, not really... It says "!ydnaM hO" I guess.

 

Oh yeah. I forgot. Bob and Doug McKensie are the debil with their backwards part of the Great White North Album. DEBIL!!!!

 

Play Princes Purple Rain Backwards- Hilarious.

 

Pokemon Rap... heh, I always knew it was the debil!!!
