Go to http://jeffmilner.com/backmasking.htm and play Stair Way To Heaven. Then play it in reverse and you'll hear him say:

Oh here's to my sweet Satan. The one whose little path would make me sad, whose power is Satan. He'll
give those with him 666, there was a little toolshed where
he made us suffer, sad Satan

Creepy!

Oh not these things again...

i went to a catholic school and i remember when i was in my senior year my religion teacher showed us a video tape about this "subliminal messages" in rock songs haha
i remember freaking out when i heard Another one bites the dust, and it said something about "you should smoke marihuana" , then we had Hotel California and like you said Starway to Heaven etc etc, it was weird, but this guy in my class listens to this kind of music and after we saw that video he started to fight with our teacher, it was crazy
i dont believe in this messages actually but who knows if its true or not :unsure:
