Post Malone adds his fourth Hot 100 leader, the most of all artists since his first in 2017.

Post Malone notches his fourth No. 1 song on the Billboard Hot 100, as "Circles" ascends from No. 2. Since scoring his first No. 1 on the chart in October 2017, his four leaders are the most among all artists.

Plus, Lizzo's "Good as Hell" hits a new Hot 100 high, lifting 4-3, as it becomes the most-heard hit on U.S. radio, rising to No. 1 on the Radio Songs chart, and Billie Eilish logs her second Hot 100 top 10, as "Everything I Wanted" vaults from No. 74 to No. 8 following its first full week of tracking.

Let's run down the top 10 on the Hot 100 (dated Nov. 30), which blends all-genre U.S. streaming, radio airplay and sales data. All charts will update on Billboard.com tomorrow (Nov. 26).

Here's a deeper look at Post Malone's new No. 1. The song, released on Republic Records, is the 1,093rd leader in the Hot 100's 61-year history.

Airplay, sales & streams: "Circles" slips 2-3 on Radio Songs, but with a 3% boost to 91.1 million audience impressions, in the week ending Nov. 24, according to Nielsen Music. It rises 6-5 on Streaming Songs with 23.4 million U.S. streams, up 2%, in the week ending Nov. 21, while dipping 5-6 on Digital Song Sales with 14,000 sold, down 7%, in the same span.

Post Malone's fourth No. 1: Post Malone adds his fourth Hot 100 No. 1, and first billed solely to the singer-songwriter and rapper. "Rockstar," featuring 21 Savage, reigned for eight weeks beginning on the chart dated Oct. 28, 2017; "Psycho," featuring Ty Dolla $ign, topped the June 16, 2018-dated ranking; and "Sunflower (Spider-Man: Into the Spider-Verse)," with Swae Lee, led the list earlier this year, on the chart dated Jan. 19.

Brightest star: Since "Rockstar" became his first Hot 100 No. 1 on the chart dated Oct. 28, 2017, Post Malone's four leaders on the list are the most among all artists, as he breaks out of a tie with Drake, who has tallied three in that span (all in 2018). Camila Cabello, Cardi B, Ariana Grande and Travis Scott follow with two each in that stretch.

Writers & producers: Post Malone wrote "Circles" with Louis Bell, Frank Dukes, Billy Walsh and Kaan Gunesberk, and produced it with Bell and Dukes.

Post Malone notches his fourth Hot 100 No. 1 as a writer (encompassing all his leaders as an artist) and second as a producer, after "Psycho." Bell achieves his seventh No. 1 as a writer and fifth as a producer, while Dukes tallies his third leader in both roles. Walsh and Gunesberk each earn their second Hot 100 No. 1s as writers.

13 lucky No. 1s in 2019: "Circles" is the 13th song to rise to No. 1 on the Hot 100 in 2019, marking the greatest total since 13 songs ascended to the summit in all of 2011. As previously noted, the relatively rapid turnover at the top this year is especially notable given that Lil Nas X's "Old Town Road," featuring Billy Ray Cyrus, blocked all challengers for a record 19 weeks (April 13-Aug. 17).

Top shape: Meanwhile, "Circles" is the second Hot 100 No. 1 with that word in its title. An earlier rock star, Billy Preston, ruled for two weeks in July 1973 with "Will It Go Round in Circles."

"Circles" dethrones Lewis Capaldi's "Someone You Loved" atop the Hot 100, as the ballad drops to No. 2 after three weeks at No. 1.

Lizzo's "Good as Hell" ascends to a new Hot 100 high (4-3) and completes its climb to No. 1, from No. 3, on Radio Songs (94.2 million, up 10%). The track is her second consecutive leader on the airplay tally, after "Truth Hurts" reigned for six weeks beginning in September. "Good" likewise becomes her second No. 1, after "Truth," on the Pop Songs airplay chart.

"Good" adds a fourth week at No. 1 on the Hot R&B Songs chart and a second frame atop Hot R&B/Hip-Hop Songs (both of which employ the same multi-metric methodology as the Hot 100).

Maroon 5's "Memories" reaches a new Hot 100 peak (5-4), while Selena Gomez's "Lose You to Love Me" rebounds 8-5, three weeks after topping the chart. The latter wins the Hot 100's top Airplay Gainer award, as it leaps 20-13 on Radio Songs (53.7 million, up 24%).

Shawn Mendes and Cabello's former one-week Hot 100 No. 1 "Señorita" slips 3-6 and Chris Brown's "No Guidance," featuring Drake, is steady at No. 7, after reaching No. 5.

Billie Eilish's "Everything I Wanted" rockets from No. 74 to No. 8 on the Hot 100 following its first full week of data tracking, after its Nov. 13 release.

The ballad claims top Streaming Gainer and Sales Gainer honors on the Hot 100 as it begins at No. 2 on Streaming Songs with 26.4 million U.S. streams Nov. 15-21 (after drawing 7.5 million Nov. 13-14) and surges 12-2 on Digital Song Sales with 17,000 sold (after selling 10,000 in its first two days of availability). Also securing 4.9 million in all-format radio reach in the week ending Nov. 24, it enters the Alternative Songs airplay chart at No. 35.

Eilish earns her second Hot 100 top 10, after "Bad Guy," which led the Aug. 24-dated chart (and currently ranks at No. 17). "Everything" is, as of now, a stand-alone single, while "Bad Guy" is from her former No. 1 Billboard 200 album, When We All Fall Asleep, Where Do We Go? Her other current single, "All the Good Girls Go to Hell," from the set, bumps 80-76 on the Hot 100, while keeping at its Nos. 6 and 20 bests on Alternative Songs and Pop Songs, respectively.

Dan + Shay and Justin Bieber's "10,000 Hours" rises 10-9 on the Hot 100, after debuting at its No. 4 peak. It jumps 12-9 on Radio Songs (63.4 million, up 10%), becoming Dan + Shay's second top 10, after "Speechless" hit No. 10 in August, and Bieber's 13th. The collaboration also hits the Country Airplay top 10 (12-10), as it crowns the multi-metric Hot Country Songs chart for a seventh week.

Rounding out the Hot 100's top 10, Lizzo's former seven-week No. 1 "Truth Hurts" drops 6-10, as it rules Hot Rap Songs for a 13th week.

Just beyond the Hot 100's top 10, Arizona Zervas' "Roxanne" roars 27-12 as his breakthrough hit becomes his first No. 1 on Streaming Songs (29.9 million, up 44%). The track also launches at No. 30 on both Pop Songs and Rhythmic Songs.

Plus, Taylor Swift's "Lover," which reached No. 10, becoming her 25th Hot 100 top 10, in September, bounds 26-15, as it adds a third total, and second consecutive, week atop Digital Song Sales, with 20,000 sold in the week ending Nov. 21, after the Nov. 13 arrival of its remix with Mendes. The ballad also re-enters Streaming Songs at No. 21 (15.9 million, up 56%) and pushes 26-25 on Radio Songs (35.2 million, up 6%).
