Eminem is the best-selling rapper of all time and the debate over his greatest song is one of the most passionate in hip hop. Lose Yourself won the Academy Award for Best Original Song and remains the greatest motivational rap song ever recorded — a desperate, furious declaration of purpose that soundtracked a generation. Stan invented a word that entered the dictionary and told a story of fan obsession with a literary quality that rap had rarely achieved. The Real Slim Shady was his most commercially successful song and his most audacious provocation. Rap God demonstrated technical skill — six verses with virtually no hooks, including a section where he raps 97 words in 15 seconds. Without Me is his most purely enjoyable song, a pop-rap masterpiece of self-deprecating chaos. Which Eminem song is truly his greatest?
