Stairway to Heaven backwards. An oldie but a goodie. Or an ode to the devil. Or something.

Tried this in school. Someone said it makes sense that it would say something demonic when played backwards. If one way's The Stairway to Heaven, the other would have to be the stairway to the other place.
Funny, whenever I tried to play my records backwards I just something along the lines, "Maaaahnnn youurrrr scrreewwwing up yuuuuur neeeeedull."
Kept trying to figure out what that meant but my record player broke...
