A PREVIEW OF RADIO CHART PREVIEWS

There's a serious chart traffic jam going on at T40 this week with no real movement in the packed Top 20, although Big Sean managed to break inside with "Bounce Back" (G.O.O.D./Def Jam), while ZAYN debuts on the chart with his newest, "Still Got Time" f/PARTYNEXTDOOR (RCA).

A Rhythm, it looks like Chris Brown's "Party" (RCA) will take the top slot while Drake's "Passionfruit" (YMCMB/Republic) will be the week's highest debut and Greatest Gainer— which is in total alignment with his record-breaking streaming numbers.

And at Modern Rock, Imagine Dragons' "Believer" (KidinaKorner) gets their second week at #1, Sir Sly's "High" (Cherrytree) has a huge debut at #24, up 400 spins and Sundara Karma's "She Said" (Bee & El/RAL/RED) will make their chart debut.
