Eminem's "Lose Yourself" was released as a single on October 22, 2002. The semi-autobiographical track tells the story of a young rapper who must overcome shyness in order to perform. The song would hit number one in November and stay there for 12 weeks, through January of the next year.“Lose Yourself” is probably the rapper's best-known track, featured in Eminem's debut film vehicle "8 Mile" and eschewing the controversial subject matter that had helped make him famous for a more straight-ahead inspirational message:You better lose yourself in the music, the moment You own it, you better never let it go You only get one shot, do not miss your chance to blow This opportunity comes once in a lifetime . . .
