A human rights group has alleged that the US played Eminem and Dr Dre to prisoners as torture.

Human Rights Watch says detainees at a secret prison near Kabul, Afghanistan were kept in dark cells and subjected to loud music. Terrorist suspects interviewed by the group say heavy metal and hip hop were used to shake them.

Ethiopian Benyam Mohammad is quoted in the report: "It was pitch black, no lights on in the rooms for most of the time. ... They hung me up. I was allowed a few hours of sleep on the second day, then hung up again, this time for two days. My legs had swollen. My wrists and hands had gone numb."

"There was loud music, [Eminem's] "Slim Shady" and Dr. Dre for 20 days," he continued. Then "they changed the sounds to horrible ghost laughter and Halloween sounds. ... The CIA worked on people, including me, day and night.... Plenty lost their minds. I could hear people knocking their heads against the walls and the doors, screaming their heads off."
