Dej Loaf - "Back It Up" feat. Big Sean

XXL Freshman and Detroit leader of the new school, Dej Loaf, continues to leave a stamp on the game and prove that she isn't a fluke as she teams up with hometown vet Big Sean for her new single "Back Up". Produced by iRock, the baseline heavy instrumental compliments Dej as she throws warnings out to anyone coming close to her. Look for both of them to hit the road this summer as she will join Nicki Minaj starting July 17 and Sean links with J. Cole on July 12.
