yesterday, my friends and I were listening to Abbey Road by The Beatles backwards, when I said, "hey, let's see if queen says anything backwards!" and sure enough, in one part of Another One Bites the Dust, it very faintly says "it's fun smoke marijuana." this was obviously an accident, but then in Bicycle Race, it more clearly says, "please bow down." weird, eh? I found out about the marijuana one on some website, but discovered the Bicycle Race one myself. To play music backwards, use sound studio.
Try playing "Sat on a fence but it don't work" from Under Pressure backwards.
It says "Little boys below, sniffin' on us" which makes about as much sense as "Sat on a fence but it don't work"
