Having kicked off the summer with the swaggering sax licks of "Problem," the former Nickelodeon star now closes it out with the hand-clapping "Bang Bang" (with a little help from Jessie J and Nicki Minaj). Ever the professional, Grande bows to collaborators while staying in control: A$AP Ferg gets told, straight up, what to do with his hands ("Don't take them off until I say so"). Elsewhere, Grande loses a beau to a man (on the Diana Ross-sampling "Break Your Heart Right Back"), then teases another ex over what he's missing ("Stay with me a minute / I swear I'll make it worth it").
