Jeff Milner, 27-year old self-described “backmasking guy,” has compiled a kickass Flash movie that allows you to hear some of the most notorious reverse song lyrics for yourself, including Led Zeppelin’s infamous “Stairway to Heaven” clip. Satan-approved fun for the whole family.

From Jeff Milner’s project statement:

“Years ago someone told me that if you played Led Zeppelin’s Stairway to Heaven song backwards that you could make out ’satanic messages’. It is not my opinion that Led Zeppelin and the other artists here were given some kind of evil power to make these backwards sounds have a satanic message. And, no, I did not create this to show the evils of Rock and Roll. Instead I made this flash piece for two reasons:

1. I was new to flash and wanted to be better at it and
2. The reverse files sound cool.”
