The new vertical video for Halsey's hit helps it surge in streaming, while Post Malone adds his sixth top 10.

Halsey's "Without Me" rebounds from No. 2 to No. 1 for a second week atop the Billboard Hot 100 chart (dated Jan. 26). The song first led the list dated Jan. 12.

"Without Me" dethrones Post Malone and Swae Lee's "Sunflower (Spider-Man: Into the Spider-Verse)," which dips to No. 2 after a week at No. 1 on the Hot 100. Still, Post Malone adds a new top 10, as solo single "Wow." rises 11-9.

Let's run down the top 10 of the newest, Jan. 26-dated Hot 100, which blends all-genre U.S. streaming, radio airplay and digital sales data. All charts will update on Billboard.com tomorrow (Jan. 23).

"Without Me," which two weeks earlier became Halsey's first Hot 100 No. 1 on her own (after she ruled for 12 weeks in 2016 as featured on The Chainsmokers' "Closer"), returns to the summit with top Streaming Gainer honors, as it pushes 3-2 on the Streaming Songs chart, up 23 percent to 47 million U.S. streams in the week ending Jan. 17, according to Nielsen Music. Aiding the advance, Halsey released a new vertical video for the song Jan. 9, just ahead of the Jan. 11-17 tracking week feeding the latest, Jan. 26-dated charts. (The song's official proper clip premiered in late October.)

"Without Me" likewise rises 3-2 on Radio Songs, up 4 percent to 106.6 million audience impressions in the week ending Jan. 20. It holds at No. 2 on Digital Song Sales, up 4 percent to 41,000 downloads sold in the week ending Jan. 17.

Post Malone and Swae Lee's "Sunflower" retreats to No. 2 on the Hot 100, a week after becoming the former's third No. 1 and the latter's first as a soloist. Still, the track tops Streaming Songs for a second week (52.8 million, up 11 percent; like "Without Me," it was also helped by a new video released Jan. 9) and Digital Song Sales for a third frame (41,000, down 14 percent). On Radio Songs, "Sunflower" lifts 10-9 (63.3 million, up 4 percent).

Thus, while "Sunflower" ranks at No. 1 on both Streaming Songs and Digital Song Sales, a notch above "Without Me" on each survey, the latter track's sizable lead on Radio Songs makes the difference in their ranks on the Hot 100.

Cartoon tunes: As noted by readers Jesper Tan and Jake Rivera, "Sunflower," from Spider-Man: Into the Spider-Verse, is only the fourth song from an animated movie to have hit No. 1 in the Hot 100's 60-year history, following "Can't Stop the Feeling!," by Justin Timberlake, from Trolls (one week, 2016); "Happy," by Pharrell Williams, from Despicable Me 2 (10 weeks, 2014); and, "A Whole New World," by Peabo Bryson and Regina Belle, from Aladdin (one week, 1993).

"Sunflower" concurrently spends a third week at No. 1 on both the Hot R&B/Hip-Hop Songs and Hot Rap Songs charts.

Meanwhile, Post Malone adds his sixth Hot 100 top 10, as "Wow." ascends 11-9 (in its fourth week on the chart). The track slips 5-6 on Streaming Songs (25.3 million, down 2 percent), elevates 10-7 on Digital Song Sales (14,000, up 5 percent) and debuts at No. 37 on Radio Songs (27.1 million, up 45 percent), as it wins the Hot 100's top Airplay Gainer award for a second consecutive week.

Elsewhere, Travis Scott's "Sicko Mode," which led the Hot 100 dated Dec. 8, rebounds 4-3 and Panic! at the Disco's "High Hopes" climbs to new peak (5-4), as it leads Hot Rock Songs for a 12th week and Radio Songs for a ninth frame (126.5 million, down 4 percent).

Rounding out the Hot 100's top five, Ariana Grande's "Thank U, Next" drops 3-5 after it spent seven nonconsecutive weeks at No. 1. As previously reported, the song takes over atop the Pop Songs airplay chart, while follow-up single "7 Rings" debuts, ahead of its likely lofty Hot 100 launch next week.

Four other songs in the Hot 100's top 10 are stationary, led by Marshmello and Bastille's "Happier," which keeps at No. 6, after hitting No. 3, as it tops Hot Dance/Electronic Songs for an 18th week.

Maroon 5's former seven-week No. 1 "Girls Like You," featuring Cardi B, repeats at No. 7 on the Hot 100, as it logs a 30th week in the region, becoming just the sixth single in the chart's history to reach that level. Here's a look at the longevity leaders:

Most weeks in Hot 100's top 10

33, "Shape of You," Ed Sheeran, 2017

32, "Closer," The Chainsmokers feat. Halsey, 2016-17

32, "How Do I Live," LeAnn Rimes, 1997-98

30, "Girls Like You," Maroon 5 feat. Cardi B, 2018-19

Capping the Hot 100's top tier, Lil Baby and Gunna's "Drip Too Hard" is steady at No. 8, after reaching No. 4, and Kodak Black's No. 2-peaking "ZEZE," featuring Travis Scott and Offset, holds at No. 10.

Outside the Hot 100's top 10, two duets debut in the top 40: French DJ/artist Gesaffelstein and The Weeknd's "Lost in the Fire" ignites at No. 27 and Sam Smith and Normani's "Dancing With a Stranger" bows at No. 33.
