You've probably noticed a lot of Olympic athletes jamming out with their headphones on moments before competition. Is this just a little last-minute entertainment? Or are they listening to specially-designed playlists to give them some sort of competitive edge?

While a song might not make the difference between gold medal and last place, science says the right music can help athletes wring out that last extra little drop of performance. And even if that's not the case, the calming effect of a favorite song can serve to distract from game-day jitters, helping the athlete achieve better focus.

Makes you wonder if any of the athletes are listening to "What Does The Fox Say" as they suit up for competition. [ASAPScience]
