During the Waco siege (1993), according to Wikipedia,
"Increasingly aggressive techniques were used to try to force the Branch Davidians out (for instance, sleep deprivation of the inhabitants by means of all-night broadcasts of recordings of jet planes, pop music, chanting, and the screams of rabbits being slaughtered)." That seems to me to put pop music in its proper company. I wonder if the FBI paid the usual royalties for a public performance.
