Prisoners at Guantanamo Bay are now being tortured with "Sesame Street."

According to a new documentary by Al Jazeera, detainees at the US Naval base have been forced to wear headphones blaring "Sesame Street" music on repeat for hours or days on end to break their will.

Award-winning "Sesame Street" composer Christopher Cerf told Al Jazeera he doesn't like the way the music is being used.
