9. Eminem - 'Lose Yourself'
Eminem took a bit of a risk when he made 8 Mile in 2002. This was near the peak of his fame, and a big-screen flop could have kicked off a downward spiral. Britney Spears and Mariah Carey both made movies right around the same time, and they were absolute disasters. Needless to say, those were terrible movies and Eminem made a pretty great one. "Lose Yourself" – a song that wraps up most of the movie's plot in five-and-a-half minutes – became his first Number One hit. It was so massive that moms across America were blasting it in their mini-vans, and it became the first hip-hop song to win an Academy Award.
