38. Lil Wayne "I'm Me" (2007)
Producer: DJ Nasty & LVM
Album: The Leak
Label: Cash Money
"I'm me!" Obviously, you're you, Wayne. But this sort of self-affirmation seems to have played a big part in Wayne's rise to popularity. He seemed to be fueled by the logic that if you keep calling yourself The Best Rapper Alive, eventually it will come true. He did and it did.
If this rap thing doesn't take off for Wayne he just might have a bright future as a motivational speaker. Surely, Olympic swimmer, Michael Phelps, who listened to this song before each race on his way to winning eight gold medals, would agree.
