Swimmer Missy Franklin's Prerace Playlist

Four-time Olympic gold medalist Missy Franklin can't listen to pump-up music before races. "If I get too amped up it kind of leaks a little energy off," she said -- and she wants to be using all her energy to set world records in the water.

Instead, Franklin, who's taking a year off from the University of California-Berkeley to prepare for the 2016 Olympics, listens to chill music. As she heads to the pool, she likes "anything country" and songs that help put the race in perspective.

She shared some of her favorite happy songs with us.
