Trent Reznor and other prominent musicians, such as Tom Morello, Pearl Jam, and REM, have asserted a formal protest against the use of their music during "enhanced interrogation" sessions at the Guantanamo Bay detainee facility and have joined the "National Campaign to Close Guantanamo," according to
this article. The group also announced plans to file a lawsuit to compel the declassification of documents concerning the use of their music. (It is certainly conceivable that blasting "Shiny, Happy People" for 72 hours straight might constitute torture, at least to some folks.)
