Control iTunes from within World of Warcraft

Well here's something I missed last week. This past Tuesday was "patch day" in the world of Warcraft. The latest patch, v. 1.12, brought several changes to the game, including the ability to control iTunes. From the Key Bindings preference window you can set up keys to control play, pause, next, back and volume from within the game. Why would you want to do that? Because that song you hear in each of the inns can get stuck in your head for a long, long time.
