A new documentary released by Al Jazeera claims that Sesame Street songs are being used to torture prisoners at Guantanamo Bay.
The documentary called Songs of War says that detainees are allegedly forced to wear headphones and listen to the songs repeatedly.
Sesame Street composer Christopher Cerf does not believe the allegations are true.
"Of course I didn't really like the idea that I was helping break down prisoners, but it was much worse when I heard later that they were actually using the music in Guantanamo to do deep, long-term interrogations and obviously to inflict enough pain on prisoners so they would talk, " said Cerf.
Heavy metal was used previously as a form of musical torture such as songs by Metallica.
