Just over a week after releasing a new single with a feature from Young ThugDej Loaf is back with yet another loosie and this time she enlisted her fellow Detroit rapper Big Sean for a guest verse. "Back Up" is just more proof that Dej has a knack for writing insanely catchy hooks and can rap with the best of them. And while we're still waiting for more info about her forthcoming debut, Loaf's latest single is at least right on time for the holiday weekend.
