With rap, it is sometimes hard to predict who's going to remain. Marco XO, a rapper out of Orlando, sounds like he has a voice (and style) with a chance to last, and, with "Mars", and it's clear he has the attributes that rap fans look for. It's our favorite release from his catalog, and we suggest that you get familiar with him, because he's likely got more heat coming. (Dive in "Mars" below, though, for now.)
