Eminem recently stopped by Sway in the Morning to help promote the film Southpaw, which hits theaters tomorrow. It stars Jake Gyllenhaal and 50 Cent. It is centered around a boxer who is looking to regain his boxing skills and life after some serious pitfalls. Eminem is the curator of the film’s soundtrack. Along with promoting the film Em also chatted it up with Sway and delivered a monstrous, brutal 8-minute freestyle. You can check that out after the jump because you know you wanna.
