What's good music for a deviated septum?

The NY Times just ran this piece on the music that surgeons like to listen to while operating. Their musical choices sometimes belie the stark, antiseptic scene I think most of us associate with the O.R. There's the talk of Mozart that you might expect, and I suppose the opera is not that much of a surprise (though it does create a more melodramatic scene than I'd like to imagine if I were the one going under the knife). Apparently, however, doctors particularly like to rock out when they're stitching a patient up--they refer specifically to loud rock and roll as "closing music". So if your sutures aren't straight, maybe ask your doctor if he was listening to Metallica.
