Robert Plant and Jimmy Page of Led Zeppelin both claim that they don't know who wrote their occultic song Stairway to Heaven. Robert Plant testified:

"Pagey had written the chords and played them for me. I was holding the paper and pencil, and for some reason, I was in a very bad mood. Then all of a sudden my hand was writing out words. · I just sat there and looked at the words and then I almost leaped out of my seat." (Davin Seay, Stairway to Heaven, p. 249).

In another account, he claims that the song just came together, as if he was being driven by some "spiritual force." He said:

"Somebody pushed my pen, I think."

One segment of the song, "Yes there are two paths you can go by, but in the long run, there's still time to change the road you're on. And it makes me wonder..." when played in reverse, says: "There's no escaping it, oh it's my sweet Satan, the one whose path makes me sad, whose power is Satan." Other parts of the song, when played in reverse, say: "I live for Satan", "The Lord turns me off," "Here is to my sweet Satan," "There's power in Satan," and "Take the 666."

In the song Houses of the Holy, Plant sings:
"Let the music be your master, won't you heed the master's call? Oh Satan."
