Hello everyone.
Well, this is very (very very) old, in fact, it's like, 30 years old.
When you play Led Zeppelins song "stairway to heaven" it plays up a satanistic message.
I noticed this a long time ago after looking at the "Urban legends
But later when I noticed that there was even more songs that played up an odd message backwards.
For example, Brittney Spear's "hit me baby one more time" wich, if you play backwards, says "Sleep with me I'm not too young".
Here is a page with some part of some tracks that plays a message if played backwards.

Do you know any other song?
What do you think about the led zeppelin example, coincidence or on purpose?
