This may be the reason ... one of the most impressive cases of phonetic reversal (aka 'backtracking'). Whether by accident or by design, it's very impressive !
There is an explanation about the technique and then some sound clips of Stairway: http://www.triplo.com/ev/reversal/ (lots more info and examples)
Phoenetic Reversal in popular music
Another One Bites The Dust
Queen's only dance hit generated a little bit of attention when it was alleged that the song contained a reversed message: "It's fun to smoke marijuana".
"Another one bites the dust" -> "It's fun to smoke marijuana"
This, if it is not already obvious, is a complete accident. The reversed phrase barely resembles "It's fun to smoke marijuana" distinctly - it would be better translated to "'s fun-a scout mare-wanna". However, the important consonants exist to make the correlation between the two easy to do. The phonetic analysis is somewhat complex - it is left as an exercise to the reader.
Stairway to Heaven
Led Zeppelin's epic "Stairway To Heaven" creates possibly the most amazing phoenetic accidents known in popular music. To further the mystery around the song, a little background is necessary.
Led Zeppelin had it's popularity in the 1970s mostly in the grass-roots rock and roll community. Influences for the band included J.R.R. Tolkien books, mystical folks stories, and the like - most of which had paganistic overtones, easily interpreted by the public as closely satanic. The growth of Led Zeppelin seemed mystical in itself - though minimal promotion was done by the group's record company Atlantic Records, the group's popularity spread by word of mouth, something not usually expected or calculated.
The song "Stairway To Heaven" became a legendary song in rock and roll music culture. Stranger than the fact that it was the most-played track in radio history, stranger than the fact that the song's length was nearly 8:00 (most radio stations played nothing over 4:00), stranger than the fact that it is a staple of rock and roll guitar players everywhere, was the way the lyrics were written. Robert Plant, the lead singer and lyric writer described it: "I just sat down next to Pagey (Jimmy Page, guitarist) while he was playing it through. It was done very quickly. It took a little working out, but it was a very fluid, unnaturally easy track. It was almost as if - uh-oh - it just had to be gotten out at that time. There was something pushing it, saying 'you guys are okay, but if you want to do something timeless, here's a wedding song for you."
What makes this song truly amazing on another level is that in a stretch of nearly one minute, you could find 7 different consecutive phonetically reversed "phrases" seeming to refer to the same subject: Satan. Never in the history of popular music has this happened before or since.
- "Your stairway lies on the whispering wind" -> "'cause I live with Satan"
- "The piper's calling you" -> "the lord turns me off"
- "And it makes me wonder" -> "there's no escaping it"
- "There's still time to change the road you're on" -> "here's to my sweet Satan"
- "Yes there are two paths"... -> "there is power in Satan"
- "It's just a sprinkling for the May Queen" -> "he will give you, give you 666"
- "There's a feeling I get" -> "i gotta live for Satan"
Knowing how difficult it is to get one phrase to phonetically reverse into something understandable, but to get seven phrases, consecutively, in a passage of lyrics that forward seems almost disturbingly pagan, all related to a similar subject, in a song that led it's life the way it did, has truly been unmatched.
The facts above lead, not surprisingly, to a mystical conclusion that had many a music critic pondering and related back to many stories about popular music: in order to succeed, you had to sell your soul to the devil. The late great blues guitarist Robert Johnson (a big influence on Led Zeppelin) had many stories around him about his drifting lifestyle, amazing guitar playing, notorious seduction of women, and selling his soul to the devil in order to succeed at them. Did some sort of evil force play a part in the writing of "Stairway To Heaven"? When reversed, does it literally translate to "Stairway To Hell" in more ways than one? As mystical and far from logic as it seems, the conclusion seems appropriate!
