Roc Nation/Columbia’s Rita Ora and her saucy new collabo featuring Chris Brown called “Body On Me” grabs over 25 adds to become this week’s big winner at Rhythm. After dropping a song virtually out of the blue, Macklemore & Ryan Lewis' “Growing Up” featuring Ed Sheeran (Macklemore/Warner Bros.) ranked #2 with 16 adds. Nelly f/Jeremih's “ The Fix” (RECORDS) pulled several stations already and it doesn't officially impact until next week. Alessia Cara's “Here” (EP/Def Jam), The Weeknd's “The Hills” (XO/Republic) and Dej Loaf f/ Big Sean's “Back Up” (IBGM/Columbia) also grab a handful of new stations.
