Sheeran's "Shape of You" leads an action-packed chart, which includes Perry's return & Rihanna's 30th Hot 100 top 10.

Ed Sheeran's "Shape of You" leads the Billboard Hot 100 (dated March 4) for a fourth total week.

Meanwhile, action abounds in the top 10, as Katy Perry's "Chained to the Rhythm," featuring Skip Marley, debuts at No. 4 and Bruno Mars, Rihanna and The Weeknd all add new top 10s. Sheeran, Perry, Mars and The Weeknd benefit from performances on the Grammy Awards (Feb. 12), while Rihanna ups her count to 30 career top 10s, a milestone that only an elite three acts have now achieved.

There's even more: Zayn and Taylor Swift set a new Hot 100 high for a song from the Fifty Shades franchise and The Chainsmokers' "Closer," featuring Halsey, has now spent more time in the top five than any other single in the Hot 100's entire 58-year history.

Following yesterday's President's Day holiday, let's kick off a very busy recap of the top 10 of the Hot 100, which blends sales, airplay and streaming data. All charts will update on Billboard.com tomorrow, Feb. 22.

"Shape," released on Atlantic Records, spends a second week atop the Radio Songs chart, up by 9 percent to 145 million in audience in the week ending Feb. 19, according to Nielsen Music, claiming the Hot 100's top Airplay Gainer award for a fifth straight week. Following his performance of the song on the Grammys, "Shape" resurges 2-1 for a fourth total week atop Digital Song Sales (200,000 downloads sold, up 74 percent, in the week ending Feb. 16). On Streaming Songs, it holds at No. 2 (37.2 million U.S. streams, up 12 percent).

"Shape," which becomes Sheeran's second No. 1 on the Pop Songs airplay chart, ushers in his third studio album, ÷, due March 3.

Zayn and Taylor Swift's "I Don't Wanna Live Forever (Fifty Shades Darker)" rises 3-2 on the Hot 100, hitting a new peak. As parent album the Fifty Shades Darker soundtrack debuts at No. 1 on the Billboard 200, following its Feb. 10 release and the arrival of the movie the same day, "Live" lifts 3-2 on Digital Song Sales (143,000, up 31 percent). It also jumps 5-2 on Radio Songs (109 million, up 10 percent), while keeping at No. 4 on Streaming Songs (21.2 million, down 7 percent).

Just as Fifty Shades Darker becomes the franchise's first Billboard 200 No. 1, besting the No. 2 peak of 2015's Fifty Shades of Grey, "Live" takes over as the highest-charting Fifty Shades Hot 100 hit; it one-ups the No. 3 peaks of the first soundtrack's "Love Me Like You Do" by Ellie Goulding and "Earned It (Fifty Shades of Grey)" by The Weeknd.

Migos' "Bad and Boujee," featuring Lil Uzi Vert, dips 2-3 on the Hot 100 following three nonconsecutive weeks at No. 1. Still, the track tops the Streaming Songs chart for an eighth week with 47.7 million U.S. streams (up 1 percent). It also leads the audio subscription services-based On-Demand Streaming Songs chart for an eighth week (17.8 million on-demand clicks, down 10 percent).

"Bad" falls 8-12 on Digital Song Sales (40,000 downloads sold, down 1 percent) and inches 16-15 on Radio Songs (60 million, down 1 percent). It additionally rules Billboard's Hot R&B/Hip-Hop Songs and Hot Rap Songs charts for a seventh week each.

Katy Perry roars onto the Hot 100 at No. 4 with "Chained to the Rhythm," featuring Skip Marley. (The debut marks the highest for a song by a lead female since Adele's "Hello" launched at No. 1 on Nov. 14, 2015.) "Rhythm," released along with its official lyric video at midnight on Feb. 10 -- followed by Perry and Marley's performance of it on the Grammys two nights later -- debuts at No. 3 on Digital Song Sales (108,000 first-week downloads sold) and No. 15 on Streaming Songs (14.7 million), while charging 35-20 on Radio Songs (50 million in audience after its first full week of tracking).

Perry scores her 14th Hot 100 top 10 and the third-highest-debuting of her 25 Hot 100 entries. She bowed higher only with "Part of Me" (No. 1, 2012) and "California Gurls," featuring Snoop Dogg (No. 2, 2010). She earns her first top 10 in nearly three years; she was last in the top 10 in January-June 2014 with "Dark Horse" (featuring Juicy J), which spent four weeks at No. 1 (marking her ninth leader).

"Rhythm," whose official proper video was released today (Feb. 21), previews Perry's forthcoming studio album, her first since 2013's PRISM, expected later this year.

Rounding out the Hot 100's top five, The Chainsmokers' "Closer" rebounds 7-5 (after 12 weeks at No. 1), and its latest move is historic, as it rewrites the record for the most weeks logged in the top five: 26, or a full six months. It passes Mark Ronson's "Uptown Funk!," featuring Bruno Mars (2015) and LeAnn Rimes' "How Do I Live" (1997-98), each with 25 top-five frames.

"Closer" also extends its record for the most weeks in the Hot 100's top 10 from a title's debut, having totaled all 29 of its weeks on the chart in the top 10 since its arrival at No. 9 on Aug. 20. Even more honors: It leads Hot Dance/Electronic Songs for a 27th week, the most at No. 1 since the chart's January 2013 inception, passing Avicii's "Wake Me Up!" (26 weeks, 2013-14).

"Bad Things" by Machine Gun Kelly and current Billboard cover star Camila Cabello drops 5-6 on the Hot 100 after reaching No. 4. It's again led by airplay, as it ranks at No. 6 on Radio Songs (92 million, down 13 percent).

Following his Grammys performance of "That's What I Like," along with his Prince tribute, Mars blasts 37-7 on the Hot 100, earning his 14th top 10. The track flies 36-5 on Digital Song Sales (85,000, up 308 percent) and wins the Hot 100's top Streaming Gainer award, debuting at No. 20 on Streaming Songs (12.4 million, up 59 percent). It also jumps 36-26 on Radio Songs (43 million, up 22 percent) and, with a 5-1 jump, becomes Mars' first No. 1 on the Hot R&B Songs chart.

"Like" is the follow-up to Mars' No. 4 Hot 100 hit "24K Magic"; as previously reported, the songs' parent album 24K Magic surges 7-2 as the Greatest Gainer on the Billboard 200.

Rihanna bounds 13-8 on the Hot 100 with "Love on the Brain," marking her landmark 30th top 10. The only acts with more? Madonna, with 38, and The Beatles, with 34. (Rihanna breaks a tie for third place with Michael Jackson, who's tallied 29 top 10s, as a soloist.)

"Brain" moves 6-5 on Radio Songs (101 million, up 7 percent); 17-18 on Digital Song Sales (36,000, up 8 percent); and 25-21 on Streaming Songs (12.6 million, up 7 percent). Perhaps aiding the song's profile in the tracking period, Rihanna received eight Grammy nominations, including best urban contemporary album for "Brain" parent set ANTI.

Want one more new Hot 100 top 10 this week? Fellow Grammys performer The Weeknd vaults 16-9 on the Hot 100 with "I Feel It Coming," featuring Daft Punk, after the acts performed the song, as well as prior single "Starboy," at music's biggest night. The song is The Weeknd's sixth Hot 100 top 10 and Daft Punk's third (and second as featured on a hit by The Weeknd, following the No. 1 "Starboy").

"Feel" ascends 16-7 on Digital Song Sales (55,000, up 65 percent); 8-7 on Radio Songs (83 million, essentially even week-over-week); and 34-28 on Streaming Songs (10.7 million, up 9 percent).

Wait, that's four new Hot 100 top 10s, by Perry, Mars, Rihanna and The Weeknd, all in one week. How rare is that kind of turnover? Four songs hadn't posted their first weeks each in the top 10 simultaneously in nearly six years: On the April 2, 2011-dated chart, The Black Eyed Peas' "Just Can't Get Enough" (22-5), Glee Cast's "Loser Like Me" (No. 6 debut), Chris Brown's "Look at Me Now," featuring Lil Wayne and Busta Rhymes (12-8), and Jeremih's "Down on Me," featuring 50 Cent (13-10), all reached the region for the first time.

And, back to 2017: Rounding out the Hot 100's top 10, Big Sean's "Bounce Back" backtracks from its No. 6 peak to No. 10. The song soared from No. 15 a week ago when his new album I Decided. debuted at No. 1 on the Feb. 25-dated Billboard 200. Meanwhile, "Bounce" becomes Big Sean's fourth No. 1 on the Rhythmic Songs airplay ranking.
