New Music: Soulja Boy & 50 Cent: "Mean Mug"

We all know that 50 Cent is cool with Soulja Boy, but it looks like the two have took it a step further with their friendship, and collaborated on a new track. Soulja and 50's joint effort is called, "Mean Mug," a more southern-sounding type record, where 50 Cent lets it be known that he definitely is riding with Soulja Boy as the two go back and forth spitting bars. Be sure to take a listen to their track!
