It looks like RCA will hold down the #1 slot for a fourth straight week—way to go— with ZAYN's "Pillowtalk." Lukas Graham's "7 Years" (Warner Bros.) and Mike Posner's "I Took A Pill In Ibiza" (Island/Republic) will battle it out for #2 . Fifth Harmony's "Work From Home" (SYCO/Epic) moves up to #6. The Chainsmokers' "Don't Let Me Down" f/Daya (Disruptor/Columbia) climbs up to #12 and Drake's "One Dance" f/Wizkid & Kyla (YMCMB/Republic) takes a leap inside the Top 20, landing at #17. Pink's "Just Like Fire" (RCA/Walt Disney) moves Top 25. Joining the chart this week in full crossover mode is Desiigner's "Panda" (G.O.O.D./Def Jam). And looking to chart on impact is Calvin Harris' "This Is What You Came For" f/Rihanna (Columbia).
