A PREVIEW OF RADIO CHART PREVIEWS

As the charts steady themselves post-holiday, there's a new #1 at T40, Ed Sheeran's "Perfect" (Atlantic). Dua Lipa's "New Rules" (Warner Bros.) surges up into the Top 10 on a 2,000+ spin gain while Big Machine/Republic's Taylor Swift joins the Top 10 this week with "End Game," featuring Ed Sheeran & Future— right on the heels of a freshly-released video.

At Rhythm, Post Malone's iconic "Rockstar" f/ 21 Savage (Republic) will return to #1 and NF's "Let You Down" (NF Real Music/Caroline) breaks the Top 5, while both N.E.R.D. & Rihanna's "Lemon" (Columbia) and G-Eazy & Halsey's "Him & I" (RCA) lock themselves inside the Top 10.

And at Modern Rock, Beck's "Up All Night" (Capitol) remains at #1, while Walk The Moon's "One Foot" (RCA) sits at #2 with enough momentum for the top spot sometime next week.
