It's a hot race to the finish for the #1 spot at Pop this week, since very few spins separate current chart-topper Omi and his song of the summer "Cheerleader" (Ultra/Columbia) from The Weeknd's "Can't Feel My Face"(XO/Republic). Rachel Platten's "Fight Song" (Columbia) will join the Top 10 along with Demi Lovato's "Cool For The Summer" (Island/Hollywood/Republic). One of this week's best spin gainers is R. City f/Adam Levine's "Locked Away" (RCA) which leaps way up inside the Top 20. Joining the chart this week will be SYCO/Columbia's One Direction with their already record-breaking "Drag Me Down," also this week's Greatest Gainer. Columbia's Calvin Harris + Disciples "How Deep Is Your Love" makes its chart debut, powered by a very hot video starring supermodel Gigi Hadid. Bubbling just under and looking to hit the Top 40 next is Nathan Sykes' "Kiss Me Quick" (Global).
