No doubt about it, "See You Again" was one of the songs of the summer last year, but the radio smash would have sounded a lot different if the Wiz Khalifa/Charlie Puth collabo had landed with the MC for which it was originally intended.

50 Cent revealed that the Fast & Furious Paul Walker tribute was originally offered to longtime collaborator Eminem, but he turned it down due to his loyalty for a competing summer film: Southpaw, last July's Jake Gyllenhaal-starring boxing movie where Em and 50 rapped on three soundtrack cuts. "At the time [Eminem] had to make a decision between doing that and the song for Fast & Furious," he explained. "That record ['See You Again'] was a huge success for Wiz Khalifa and them. [Eminem] decided to do Southpaw because he was invested in the project."
