I was just surfing the net a few days ago, looking for the reversed audio to Hotel California (Eagles) which, my friend had claimed, contained satanic messages when played backwards. Of course, this was one of my favourite songs and I was skeptical, but I decided to search anyway. I came across this (
http://jeffmilner.com/backmasking.htm) site which had the straight as well as reversed audio to certain songs which made sense backwards, and more than half of them did contain satanic messages. This was supposedly a method called backmasking.
Now my question here is, what exactly is the point in backmasking satanic things into songs? Some people say it affects you negatively through subliminal manipulation, but I've never had any problems with California.
I also heard that the cover 'Am I Evil' by Metallica is also satanic when you play the chorus backwards. This one I tried reversing myself and it was true.
