There's not much movement inside the Top 10 this week, but Katy Perry's "Chained To The Rhythm" (Capitol) and Marian Hill's "Down" (Photo Finish/Republic) are both knocking on the door, waiting to join that elite group. The Chainsmokers & Coldplay's "Something Just Like This" (Disruptor/Columbia) jumps up from #26 to #18 while James Arthur's "Say You Wont Let Go" (Columbia) also joins the Top 20. Linkin Park's "Heavy" f/Kiiara (Warner Bros.) also rises inside the Top 20. Columbia has two tracks charting, Calvin Harris f/Frank Ocean & Migos' "Slide" and Train's "Play That Song".
