Now, a new documentary from Al Jazeera shows that detainees may also have been subjected to musical torture of a softer variety.
According to the report, prisoners at the U.S. detention camp at Guantanamo Bay Naval Base were forced to wear headphones blasting music from Sesame Street on repeat for hours or days on end.
Christopher Cerf, the award-winning composer of Sesame Street, was stunned to learn how his music was being exploited.
"My first reaction was this just can't possibly be true," he told Al Jazeera. "...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 actually do deep, long-term interrogations and obviously to inflict enough pain on prisoners so they would talk."
This isn't the first time that music from Sesame Street has been used to break the will of prisoners. In 2003, the U.S. reportedly used the soundtrack to soften up Iraqi POWs.
Sesame Street, an educational children's television series, has been on the air since 1969.
