Perhaps the most well-known song of Eminem's career, “Lose Yourself” never gets old. Slim performed the fiery classic track for a loyal Detroit crowd during his "Relapse" tour in 2009. Unsurprisingly, camera's spanning the crowd showed all attendees echoing every word of the song. Though Em was still recovering his stage presence after lapses of inactivity, he proved he could still put on one hell of a show.
