Camilla Cabello's "Havana" (Syco/Epic) will remain at the top of the pop chart for a fourth week in a row—a nice way to close out the last airplay ranking of the year. Ed Sheeran's "Perfect" (Atlantic) is the Greatest Gainer and moves up to #2, while label mate Charlie Puth joins the Top 10 with "How Long." Taylor Swift's "End Game" f/Ed Sheeran & Future (Big Machine/Republic) and NF's "Let You Down" (NF Real Music/Caroline) climb inside the Top 15. Khalid's "Young Dumb & Broke" (Right Hand Music Grp/RCA) joins the Top 20. Big movers inside the Top 30 include Bebe Rexha's "Meant To Be" f/FGL (Warner Bros.) and G-Eazy & Halsey's "Him & I" (Capitol/RCA). Joining the final chart of 2017 will be BTS' "Mic Drop" (Aoki Mix) f/Desiigner (Big Hit Ent/RED) and Demi Lovato's "Tell Me You Love Me" (Hollywood/Island/Republic).
