Ordinarily, when rappers are added to original tracks, we're not given enough reason to think any differently of the versions we've already heard. We're left dissatisfied as a result, and we ultimately have no reason to replay the track(s). Thankfully, up-and-coming artist Stephen has not fallen into that trap with the second part of "Crossfire", because, though its original framework remains, its addition of Talib Kweli and KillaGraham ensures there's enough added to it to make it appealing again.
