I´ve never believed in that messages in song backmasked.... but after hearing this.... it´s not like a word or too.... it´s like you said before.... it´s all the song!! and very clear.... so I did some research....
I´ve always thought that was how you hear the song backward.... but I found out in internet... that is not.... the messages could be taped over the backward song....
this is from wikipedia
Artists often use backmasking of sounds or instrumental audio to produce interesting sound effects.[35][53] One such sound effect is the reverse echo. When done on tape, such use of backmasking is known as reverse tape effects. One example is Matthew Sweet's 1999 album In Reverse, which includes reversed guitar parts which were played directly onto a tape running in reverse.[54] For live concerts, the guitar parts were played live on stage using a backward emulator.[55]
A common use of backmasking is hiding a comedic or parodical message backwards in a song.
Pink Floyd dropped a backmasked message into "Empty Spaces", from 1979's The Wall:
-... Congratulations. You have just discovered the secret message. Please send your answer to Old Pink, care of the Funny Farm, Chalfont...
-Roger! Carolyne's on the phone!
-Okay.
So I think he could have done it this year.... for us..... :D
