A PREVIEW OF RADIO CHART PREVIEWS

Will the current #1 at T40, Shawn Mendes' "There's Nothing Holdin' Me Back" (Island/Republic), be able to hold off the fast-rising single "Attention" from Charlie Puth? Count on a tight fight to the end, while Sam Hunt's "Body Like A Back Road" (MCA Nashville/Capitol) moves into the Top 10 and Demi Lovato's "Sorry Not Sorry" (Hollywood/Island/Republic) joins the Top 20.

For a third straight week at Rhythm, Team Epic dominates the top two slots, with DJ Khaled f/ Rihanna's "Wild Thoughts" (We The Best) and French Montana's "Unforgettable" f/Swae Lee (Eardruma/Bad Boy/Interscope) locked in position, as Logic's "1-800-273-8255" f/Alessia Cara and Khalid (Def Jam) moves up inside the Top 10.

And at Modern Rock, there is truly no stopping Portugal. The Man's "Feel It Still" (Atlantic) as it goes on its ninth week at #1, while Island/Republic's Killers arrive in the Top 5 with "The Man."
