Hidden Message
As any quick internet search will turn up, the clip in question is from the end of the Judas Priest song "Beyond the Realms of Death". Knowing this, it's easy to figure out the words when played forwards (I'll give you a hint, it's the title of the song).
Played backwards, you are supposed to be able to hear the words "I took my life". Knowing this, it's very easy to hear these words while listening to the clip. This doesn't really mean much though, if you've ever searched for misheard lyrics on youtube you know what I mean.
Personally, all I heard was gibberish while playing the song either forwards or backwards until I looked it up and figured out what the song was supposed to be saying.
Here are the clips I got from my code:
Media:Judas_Priest_Reversed_ECE301Fall2008mboutin.ogg
Media:Judas_Priest_Reversed_(Half_time)_ECE301Fall2008mboutin.ogg
