Music = Performance Enhancing Drug?

A number of sources are reporting on a Baltimore Sun story pointing out that Olympic athletes in Torino are acting as unwitting billboards for Apple’s iPod. Most interesting is the fact that the athletes have not only been using the device as they train and prepare to compete but also are, in some cases, wearing the devices as they’re competing.

I have to wonder, given the known effect that music has on the brain, couldn’t this count as a “performance enhancing drug”?
