Singer Rosanne Cash, the band R.E.M. and guitarist Tom Morello of Rage Against the Machine are among a group of musicians who've signed on with the group New Security Action's "close Gitmo now" movement.

And they're specifically protesting the use of their songs to wear down suspected terrorists (by playing them repeatedly, at high volume) who've been detained at Guantanamo Bay or other sites.

"It seems so obvious," Cash says in a statement. "Music should never be used as torture. It's beyond the pale. It's hard to even think about."

Among the actions the musicians have joined: A Freedom of Information Act request for "all secret government records pertaining to how music was utilized as an interrogation device," according to a statement from New Security Action.

As we noted first thing this morning, former vice president Dick Cheney has a very different opinion about the interrogation methods used in recent years.
