"Girls" reigns for a second week & earns a rare honor atop the Radio Songs chart.

Maroon 5's "Girls Like You," featuring Cardi B, spends a second week at No. 1 on the Billboard Hot 100 chart (dated Oct. 6). As it rules, it joins an elite selection of hits that have led the Radio Songs chart for at least 10 weeks.

The song fends off Juice WRLD's "Lucid Dreams," which hits a new No. 2 high in its 20th week on the Hot 100, thanks to its latest gains in streaming and airplay.

Let's run down the top 10 on the newest Hot 100, which blends all-genre U.S. streaming, radio airplay and digital sales data. All charts will update on Billboard.com tomorrow (Oct. 2).

As it holds at No. 1 (in its 18th week) on the Hot 100, "Girls" tops the Radio Songs chart for a 10th week, with 128 million in audience in the week ending Sept. 30, essentially even week-over-week, according to Nielsen Music. It becomes the 10th song by a duo or group to top Radio Songs for at least 10 weeks since the Radio Songs chart launched in December 1990. (Notably, four of the 10 songs by duos or groups to rule Radio Songs for at least 10 weeks each belong to Boyz II Men):

Goo Goo Dolls' "Iris" holds the longevity record at No. 1 on Radio Songs among all acts, while Maroon 5's "Girls" boasts the longest run atop the chart by any act since Ed Sheeran's "Shape of You," which spent 12 weeks at No. 1 in 2017.

Overall, "Girls" is the 36th of 268 total Radio Songs No. 1s to rule for double-digit weeks, a feat that, thus, 13 percent of all the chart's No. 1s have attained.

"Girls" rebounds 4-3 on Digital Song Sales (24,000 downloads sold, up 14 percent, in the week ending Sept. 27), after leading for six weeks, and slides 10-13 on Streaming Songs (22.9 million U.S. streams, down 10 percent, in the week ending Sept. 27), where it reached No. 5.

A week earlier, the song became the first pop hit to top the Hot 100 since January, ending a record run of 34 consecutive weeks in which rap songs had ruled the chart.

Juice WRLD's "Lucid Dreams" hits a new No. 2 Hot 100 peak, rising from No. 4 in its 20th week on the chart; it previously ranked as high as No. 3 on July 7. The track (which samples Sting's 1993 song "Shape of My Heart") returns for a second week at No. 1 on Streaming Songs (41.6 million, up 5 percent), after having first led the list dated June 23.

Airplay continues to build for "Dreams," which rises 10-9 on Radio Songs (63.9 million, up 8 percent). As for individual formats, it lifts 3-2 on Rhythmic Songs, enters the top 10 on Pop Songs (11-10) and pushes 12-11 on Mainstream R&B/Hip-Hop.

On Digital Song Sales, "Dreams" dips 15-16 (11,000, down 5 percent).

Maroon 5's "Girls" defends the Hot 100's summit despite its 2 drop in overall activity, while Juice WRLD's "Dreams" gains by 5 percent, perhaps previewing a closer battle next week.

"Dreams" concurrently spends its first week at No. 1 on both the Hot R&B/Hip-Hop Songs and Hot Rap Songs charts, marking Juice WRLD's first leader on each list.

Post Malone's "Better Now" likewise hits a new Hot 100 high (in its 22nd week), rising 5-3, despite drops in all metrics. Airplay leads the way for the track, which logs a third week at its No. 2 peak on Radio Songs (102.2 million, down 5 percent).

Notably, the steady Hot 100 ascents for "Lucid Dreams" and "Better Now" are fairly atypical. "Dreams" is just the 10th song this decade to reach the top two in at least 20 weeks (of 139 total top-two hits since January 2010). As for "Better," it's one of 13 songs in that span to hit the top three in 22 or more weeks (of 185 top-three titles).

Drake's "In My Feelings" falls 2-4 on the Hot 100, after 10 weeks at No. 1, and Eminem's Machine Gun Kelly diss track "Killshot" slips to No. 5 after debuting a week ago at No. 3. "Killshot" logs a second week at No. 1 on Digital Song Sales (53,000, up 37 percent), while falling 2-7 on Streaming Songs (32.6 million, down 36 percent).

Rounding out the Hot 100's top 10, Travis Scott's "Sicko Mode" rises 9-6, after hitting No. 4; Cardi B, Bad Bunny and J Balvin's former No. 1 "I Like It" descends 6-7; 6ix9ine's "FEFE," featuring Nicki Minaj and Murda Beatz, is steady at No. 8, after reaching No. 3; Kanye West and Lil Pump's "I Love It" drops 7-9 after debuting at No. 6 two weeks ago; and 5 Seconds of Summer's first Hot 100 top 10, "Youngblood," holds at its No. 10 high. As previously reported, "Youngblood" becomes 5SOS' first No. 1 on the Pop Songs airplay chart.

Just below the Hot 100's top 10, three songs ascend to the top 20 for the first time: Lil Peep and XXXTentacion's posthumous collaboration "Falling Down" (47-13, following its first full week of tracking); Marshmello and Bastille's "Happier" (31-15), as it leads the Hot Dance/Electronic Songs chart for a second week; and Ella Mai's "Trip" (21-18), following her debut hit "Boo'd Up," which rose to No. 5 on the Hot 100 in July.
