For the first time since May, there's a new number one song in the US Billboard Hot 100 chart.
After 16 weeks at the top -- a record feat it shares only with Mariah Carey and Boyz II Men's "One Sweet Day" -- Luis Fonsi and Daddy Yankee's "Despacito" ceded its place in the summit to Taylor Swift.
Swift's "Look What You Made Me Do" was streamed 84.4 million times in the US (the most for any female artist), had an all-format airplay audience of 64 million, and hit 353,000 downloads during its first full week of tracking, according to Nielsen Music.
It leapt from 77th, and is Swift's fifth song to lead the Hot 100.
"Look What You Made Me Do" was released August 24 and is the lead single for the pop star's upcoming album, "Reputation," due out this November.
"Despacito," which featured Justin Bieber, drops to No. 2. It remains tied with "One Sweet Day" for the record of most weeks spent in the apex throughout the chart's 59-year history.
It was downloaded 76,000 times, had an airplay audience of 87 million, and streamed 39.5 million on its 17th week.
The other newcomers in the chart this week are Logic's "1-800-273-8255," featuring Alessia Cara and Khalid (9th), and Liam Payne's "Strip That Down" (10th).
The Billboard Hot 100 chart determines its rankings based on downloads, all-format airplay, and streaming activity.
