According to reports Eminem's newest single "Not Afraid," from his upcoming album Recovery, entered the Hot 100 at #1. Which means that Eminem is the second rap song ever to debut at #1, following "I'll Be Missing You" by Puff Daddy & Faith Evans (featuring 112) in 1997. "Not Afraid" is Eminem's third #1 on the Hot 100, following "Lose Yourself," his Oscar-winning smash from 8 Mile, and "Crack A Bottle," his collaboration with Dr. Dre and 50 Cent. (source)
