I just figured out that there is a Hidden Track on Folie a Deux!! To find it all you have to do is put the CD in a CD player and go to track one. Then, hold down the rewind button and you will hear the hidden track. Rewind to the beginning of the song and then shut up and listen!
ps. the song is called "Lullabye"
Edit: Lullabye is now available on iTunes! I guess FOB figured out that Lulabye is too beautiful of a song to remain hidden lol
