I’m sorry I have to be the one to tell you, but its officially winter. Gone (for most of the country) are the days of outside activities, bathing suits and picnics. Despite the long, cold season ahead, ATL hitmaker B.o.B is keeping summer alive with the release of Just A Sign, a standout selection from May’s Strange Clouds album. Joining Bobby Ray, whose hook vocals are undeniably catchy, is frequent collaborator Playboy Tre, who pays tribute to a fallen friend over an airy Mike Will-produced beat. Be sure to cop Strange Clouds, if you haven’t already, and don’t forget to download B.o.B’s new mixtape F**K Em We Ball, which dropped earlier this month and is available for stream/download at DJBooth.
