The Top 5 will stay fairly intact this week, with the exception being RCA’s Khalid moving to #4 with "Better." Post Malone's “Wow” (Republic) will enter the Top 10, while Gesaffelstein & The Weeknd's “Lost In The Fire” (Columbia-Republic) will be inside the Top 20. Look for 21 Savage's “A Lot” f/ J Cole (Slaughter Gang/Epic) as well as City Girls' “Twerk” f/ Cardi B (QC/Motown/Capitol) to have 300+ spin gains. Ariana Grande's “7 Rings” (Republic), Kid Ink's “Yuso” f/ Lil Wayne & Saweetie (RCA) and Tory Lanez' “Ferris Wheel” f/ Trippie Redd (Mad Love/Interscope) will all debut this week.
