"Bang Bang," reigning pop queens' Jessie J, Ariana Grande and Nicki Minaj late entry Song of the Summer contender which will be added to late-summer pop radio rotations beginning tomorrow morning, has leaked a little early. Incessantly upbeat and brassy girl power anthem, it was produced by an all-star team including Max Martin, Savan Kotecha and Ilya Salmanzadeh. Nicki, of course, makes sure to get a Myx Moscato plug into her rapped verse. "Bang Bang" will appear on Jessie J's forthcoming LP and on the deluxe edition of Grande's My Everything.
