If you listen to "'Till I Collapse" while at the gym, you will break every one of your personal records by 200 percent. The combination of the surging instrumental, Eminem's dazzling multi-syllabic rhyme schemes and Nate Dogg's baritone chorus unleash a rush of endorphins that makes a runner's high seem like a speed walker's buzz. Who needs a strict regiment of bull shark testosterone injections when you have this song?
