Taylor Swift's 'Look' Could Land Biggest Weekly Sales & Streams This Year on Way to No. 1 on Billboard Hot 100

Her return single is set to soar in atop the Streaming Songs & Digital Song Sales charts.

Taylor Swift's new single, "Look What You Made Me Do," should blast to No. 1 on next week's Billboard Hot 100 chart (dated Sept. 16) with the highest weekly sales, and possibly the top streaming total, for any song in 2017.

Highlights of the chart will post on Billboard.com on Tuesday, Sept. 5 (a day after the Labor Day holiday).

Following a first chart week of sales and streaming data tracking (Aug. 25-31), after its Aug. 25 arrival, the first single from Swift's album Reputation, due Nov. 10, could sell upwards of 400,000 downloads in its first week. That would roar past the current high for 2017: 240,000 (according to Nielsen Music), set by Ed Sheeran's "Shape of You" when it bowed atop the Hot 100 and Digital Song Sales charts dated Jan. 28.

"Look" should also launch at No. 1 on Streaming Songs with more than 60 million U.S. streams in the tracking week, challenging for the top weekly sum this year. Luis Fonsi and Daddy Yankee's "Despacito," featuring Justin Bieber, boasts the current top streaming frame of 2017: 69.6 million (June 17). Fueling the first-week streaming totals for "Look," its lyric video arrived Aug. 25 and its official clip posted Aug. 27 following its premiere during that night's MTV Video Music Awards.

"Look" could also surpass the all-time top weekly streaming sum for a song by a woman: Adele's "Hello" leads with 61.6 million in its debut week (Nov. 14. 2015).

"Look" should additionally rank in the top 15 on the Radio Songs chart with more than 50 million in all-format airplay audience.

(The Hot 100 measures airplay on a Monday-Sunday schedule, while streams and sales cover a Friday-Thursday period; thus, "Look" debuted at No. 77 on the Sept. 9-dated chart from its first three days of airplay.)

With those projected totals, "Look" appears set to dethrone "Despacito," which this week, on the Sept. 9-dated Hot 100, logged its record-tying 16th week at No. 1, matching Mariah Carey and Boyz II Men's "One Sweet Day," which reigned for 16 weeks in 1995-96, for the longest rule in the Hot 100's 59-year history.

Check back Tuesday, Sept. 5, for your first look at Swift's likely leap to No. 1 on the Hot 100 and its finalized lofty sales, streaming and airplay totals for the week.
