Taylor Swift's New Single Was Most-Played Song on U.S. Radio Friday

Taylor Swift's new single, "Look What You Made Me Do," is off to a predictably fast start, according to Nielsen Music. On the song's first full day of airplay Friday (Aug. 25), it was the most-played and most-heard song across all U.S. terrestrial radio stations monitored by Nielsen Music.

On Friday, "Look" garnered 4,228 plays -- ahead of the day's second-most-spun track, Charlie Puth's "Attention," with 4,067 detections. "Look" also earned 27.3 million audience impressions, ahead of the tune with the second-largest audience, DJ Khaled's "Wild Thoughts," featuring Rihanna and Bryson Tiller, with 19.98 million.

For comparison's sake, the most-heard song on U.S. radio in the week ending Aug. 20 was "Wild Thoughts," with 137.76 million impressions.

The first day of airplay for "Look What You Made Me Do" benefited from hourly play across an array of radio stations -- following other superstar releases like Lady Gaga's "Perfect Illusion," Britney Spears' "Make Me" and Adele's "Hello."

It's expected that "Look" will debut on the Pop Songs airplay chart dated Sept. 9, reflecting airplay spins on mainstream top 40 radio in the tracking week ending Aug. 27. (Meaning: It will debut from a little more than three days of airplay.) The song also likely already has garnered enough airplay audience to enable a bow on the next all-format Radio Songs chart, which ranks the tracks with the most audience impressions for the week.

Further, the track could also debut from only airplay on the Sept. 9-dated Billboard Hot 100 chart, which ranks the week's biggest songs based on a blend of airplay, sales and streams. The Hot 100's tracking week for airplay runs Monday through Sunday each week, while the chart's sales and streaming week runs Friday through Thursday. So, "Look" could arrive on the next Hot 100 from only airplay, as the song made its sales and streaming debut at midnight ET on Aug. 25 -- the first day of the sales and tracking week of the Sept. 16-dated Hot 100.
