You know what Big Boi's "Shutterbugg" did definitely NOT need? A mush-mouthed verse from Rick Ross. But that's what it got via a new mashup mixtape, called Southernplayalisticmaybachmusic, that mashes up Rick Ross verses with Big Boi songs and vice versa. It's a goofy idea that sounds worse in practice. Listen at 2DopeBoyz. The mixtape is due out sometime today.
