Fresh off a hotly-memed video, Drake's "Hotline Bling" (YMCMB/Republic) holds the #1 spot again this week at Rhythm, while Macklemore & Ryan Lewis' "Downtown" (Macklemore/Warner Bros.), Justin Bieber's "What Do You Mean?" (RBMG/Def Jam), Alessia Cara's "Here" (Def Jam) and Post Malone's "White Iverson (Republic) all make strong pushes inside the Top 10. Chris Brown's "Zero" and RCA label mate/duet partner Tinashe with new single "Player" f/ Chris Brown, will both be up over 300 spins. Look for Shawn Mendes' "Stitches" (Island) to debut along with a possible debut from Meghan Trainor's "Like I'm Gonna Lose You" (Epic). Two incredible songs should be on your desk today: Justin Bieber's next single "Sorry" and Adele's first song in four years, "Hello" (XL/Columbia).
