Interrogators at Guantanamo Bay, Cuba, have used Christina Aguilera's music to keep at least one detainee from sleeping, or to wake him up.

Time magazine reported that U.S. interrogators used a variety of methods involving placing stress on detainees -- including waking one sleeping detainee by dripping water on his head or playing Aguilera's records.

The magazine said Secretary of State Donald Rumsfeld approved stronger coercive methods in December 2002 for U.S. military personnel to interrogate detaines. Approval for the harsher measures was revoked in January 2003 after military lawyers in Washington, D.C., raised questions about their use, the magazine said.
