Highway To Hell backwards is pretty interesting. Stairway To Heaven is kinda scary. there is a beatles song that started off as backwards and played backwards its forwards.
Sometimes I wonder if the song writers are hiding something... Maybe they are all satanics? Some of them aren't though, some are funny, (except for the brittany spears one)
Maybe the song authority people (or whatever they are) are possessed? So they find all the songs that can be played backwards and make them popular? I don't know. And I always wondered why brittany spears always... Ugh. Just listen to her song being played backwards.
