There's not much movement in the Top 20 at T40 this week, it just looks like a game of musical chairs with most retaining their bullets but staying in place. However, G.O.O.D/Def Jam's Big Sean managed to sneak inside the Top 20 with "Bounce Back." Starley's "Call On Me" (Epic) and Calvin Harris' "Slide" f/ Frank Ocean and Migos (Columbia) both move up inside the Top 30 with good momentum. And charting this week will be ZAYN's newest, "Still Got Time" f/PARTYNEXTDOOR (RCA).
