In _1984_ music is not used for torture, altho there is mention of a Hate Song, an anthem (Oceania, 'Tis for Thee), and sentimental love songs written by machinery for the proles.

In the real world, however, I have read that subsequent developments in popular music, which Orwell was spared, were used by the FBI & BATF to deprive the inhabitants of that commune in Waco of their sleep & sanity, and subsequently by the U.S. Army for the same purpose in prisons in Iraq (I had not heard about Noriega). I am gratified to know that three agencies of my government agree with me about what recent popular music is good for, but I do wonder about one delicate legal point. Does such a use count as a public performance? And if so, were the copyright owners duly paid?
