It looks like it might be another week before Luis Fonsi & Daddy Yankee's "Despacito" f/Justin Bieber (UMLE/RBMG/Def Jam/Republic) slides into that #1 slot at T40. Halsey's "Now or Never" (Astralwerks/Capitol) will take a huge jump inside the Top 10, potentially landing inside the Top 5. Ed Sheeran's "Castle On The Hill" (Atlantic) is now Top 10. Sam Hunt's "Body Like A Back Road" (MCA Nashville) moves Top 20, along with DJ Khaled's "Wild Thoughts" f/Rihanna & Bryson Tiller (We The Best/Epic). Calvin Harris' "Feels" f/ Pharrell, Katy Perry and Big Sean (Columbia) leaps Top 25. Bruno Mars' "Versace On The Floor" (Atlantic) joins the Top 30. Charting this week should be Logic's "1-800-273-8255" f/Alessia Cara & Khalid (Def Jam) and Bebe Rexha's "The Way I Are" f/Lil Wayne (Warner Bros.).
