Add recap tease

YOUR RADIO ADD RECAP: The Jessie J + Ariana Grande + Nicki Minaj trio is going through radio like a hot knife through butter (or Marmalade, if you prefer), as "Bang Bang" (Lava/Republic) earns #1 Most Added honors at Top 40 and Rhythm. Republic's Weezer, meanwhile, takes the Alternative format back to its "Shack." There's also big action on Epic's Meghan Trainor and KONGOS, Def Jam's Jeremih f/YG, RCA's Usher, Virgin's Bastille and more; peruse our recap here, and then bust out the good scotch. (7/29p)
