Lil Wayne, "I'm Me": One of the songs from the 2008 games I listened to. Just the name of the song made sense to me, given where I'm at right now, and how I felt at these Games.
Afrojack and Steve Aoki, "No Beef": Just a great song. Fast beat, really gets you going and fired up.
Avicii, "Levels": Swimming a multiple-event program requires you to conserve and manage emotional and physical energy, so you've got the goods when you need it most. It's all about levels.
Young Jeezy, "Go Getta": Another song I listened to in 2008. Dream, plan, reach, baby – gotta go get it!
Lil Wayne, "Right Above It": That song made me want to finish strong and look forward to life after swimming.
