Swift leads again with "Look What You Made Me Do," while Smith scores his highest entrance.

Taylor Swift's "Look What You Made Me Do" rules the Billboard Hot 100 chart (dated Sept. 30) for a third week.

Meanwhile, Cardi B's "Bodak Yellow (Money Moves)," at No. 2 on the Hot 100, becomes the most-streamed song of the week, reaching No. 1 on the Streaming Songs chart, and Sam Smith soars onto the Hot 100 at No. 5 with "Too Good at Goodbyes," marking his highest debut and fifth top 10. The track also launches atop the Digital Song Sales chart as the week's best-selling download.

As we do every Monday, let's run down the top 10 of the Hot 100, which blends all-genre streaming, airplay and sales data. All charts will update on Billboard.com tomorrow (Sept. 19).

"Look," released on Big Machine/Republic Records as the lead single from Swift's sixth studio album, Reputation, due Nov. 10, remains atop the Hot 100 despite not leading any of the chart's three main component rankings. It dips 1-2 on Streaming Songs with 39.9 million U.S. streams, down 35 percent, in the week ending Sept. 14, according to Nielsen Music, and holds at No. 2 on Digital Song Sales with 69,000 downloads sold, down 39 percent, in the week ending Sept. 14. (The song led the lists for two weeks and one week, respectively.) On Radio Songs, "Look" lifts 13-10 with 75 million all-format audience impressions, up 11 percent, in the week ending Sept. 17, becoming Swift's 13th top 10 on the airplay ranking.

It's rare, but not entirely uncommon, for a song to top the Hot 100 but not be a week's No. 1 title in streaming, airplay or sales (while still accumulating enough overall chart points to reign). Bruno Mars' "That's What I Like" last did so, leading the Hot 100 dated May 13, when it ranked No. 2 in both airplay and sales and No. 4 in streaming.

Cardi B's "Bodak Yellow" holds at its No. 2 high on the Hot 100 and takes over at No. 1 on Streaming Songs with 40.8 million U.S. streams (despite a 12 percent decline). It falls 8-12 on Digital Song Sales (30,000, down 14 percent) and bullets at No. 16 on Radio Songs (57 million, up 2 percent). The rapper's breakthrough hit spends a fifth week at No. 1 on the Hot Rap Songs chart and a third week atop Hot R&B/Hip-Hop Songs.

Logic's "1-800-273-8255," featuring Alessia Cara and Khalid, hits a new Hot 100 peak, pushing 5-3. The positive-message song, whose title doubles as the National Suicide Prevention Lifeline and which gained further momentum after the trio performed it at the MTV Video Music Awards Aug. 27, rises 5-3 on Streaming Songs (34.2 million, up 12 percent); 4-3 on Digital Song Sales (51,000, although down 17 percent); and 33-29 on Radio Songs (41 million, up 16 percent).

All three acts on "1-800" hit new career highs on the Hot 100, while Cara breaks a tie with her prior best rank: her debut hit "Here" reached No. 5 in early 2016.

Luis Fonsi and Daddy Yankee's "Despacito," featuring Justin Bieber, descends 3-4 on the Hot 100 after spending a record-tying 16 weeks at No. 1. Still, it tops the Hot Latin Songs chart for a 33rd week.

Smith's "Too Good at Goodbyes" blasts onto the Hot 100 at No. 5, arriving at No. 1 on Digital Song Sales with 90,000 sold. Smith scores his second leader on the sales tally, following "Stay With Me," which spent two weeks on top in 2014. On the Hot 100, Smith easily lands his highest debut (toppling his prior best, set when "Omen," by Disclosure featuring Smith, began at No. 64 in 2015). He notches his fifth Hot 100 top 10, following "Latch," also by Disclosure featuring Smith (No. 7, 2014); "Stay" (No. 2, 2014); "I'm Not the Only One" (No. 5, 2014); and "Lay Me Down" (No. 8, 2015).

"Goodbyes" starts at No. 10 on Streaming Songs (20.8 million first-week U.S. streams), where it's Smith's fourth top 10, and ranks at No. 35 on Radio Songs (35 million, up 38 percent) following its first full week of tracking. As previously reported, the song debuts as the British singer-songwriter's sixth No. 1 on the Official UK Singles chart.

"Goodbyes" is the lead single from Smith's forthcoming sophomore LP. "The whole album is about many different things, but I wanted to open up with this [song] because it's about me, and I think that's where I left people," Smith says. "I just wanted to come back with something that updated you on my love life, which is still going terribly."

Rounding out the Hot 100's top 10, DJ Khaled's "Wild Thoughts," featuring Rihanna and Bryson Tiller, is steady at No. 6 after peaking at No. 2 for seven weeks, while leading the Hot R&B Songs chart for an 11th week; French Montana's "Unforgettable," featuring Swae Lee, rebounds 9-7 on the Hot 100, after reaching No. 3; Charlie Puth's "Attention" slips 7-8 on the Hot 100, after reaching No. 5, and tops Radio Songs for a second week (124 million, down 2 percent); Imagine Dragons' No. 4-peaking "Believer" backtracks 8-9 on the Hot 100, while ruling the Hot Rock Songs chart for a 28th week; and Shawn Mendes' "There's Nothing Holdin' Me Back" holds at No. 10, after hitting to No. 6.

Just outside the Hot 100's top 10, three songs hit new peaks in the top 20: Niall Horan's "Slow Hands" (15-11); Portugal. The Man's "Feel It Still" (18-14); and J Balvin and Willy William's "Mi Gente" (22-19).

Meanwhile, the Hot 100's top three debuts after Sam Smith belong to Zayn's "Dusk Till Dawn," featuring Sia (No. 44); Kelly Clarkson's "Love So Soft" (No. 62); and Blake Shelton's "I'll Name the Dogs" (No. 73).
