Team Def Jam knocks Rihanna's "Work" f/Drake out of the park on impact date, locking in nearly every station. The next closest competitor was Post Malone's "Too Early" (Republic) and newcomer ZAYN with his debut solo single "Pillowtalk" (RCA). Alessia Cara's "Wild Things" (Def Jam) and Mike Posner's "I Took A Pill In Ibiza" (Island/Republic) nab 7 adds each.
