Oh god, I love that. It really does sound like that, too. But I've read some "lyrics" that some guy made for the backwards Stairway, and honestly, it sounded nothing like what he said it did.

Oh, I found the link: here it is.
It sounds absolutely nothing like what he says it does. In fact, nothing in the song sounds like anything like anything until the 'my sweet satan' part.
In case anyone wants to listen to it backwards, here's an MP3 of it.

I also attached a wav of just the sweet satan part I know you could get it from Tony's link, but again, I don't think the rest sounds anything like what they say it does. Must be the drugs...
