The rapper earns his first leader on the list.

Roddy Ricch's "The Box" tops the Billboard Hot 100, rising from No. 3 to become the rapper's first No. 1 on the ranking.

Plus, Justin Bieber jumps onto the Hot 100 at No. 2 with his new single, "Yummy," following its first full week of tracking after its Jan. 3 release.

Let's run down the top 10 of the newest Hot 100, which blends all-genre U.S. streaming, radio airplay and sales data. All charts (dated Jan. 18) will update on Billboard.com tomorrow (Jan. 14).

"The Box," released on Bird Vision/Atlantic Records, is the 1,096th No. 1 in the Hot 100's 61-year history. Roddy Ricch (real name: Rodrick Wayne Moore, Jr.) wrote the song with Samuel "30Roc" Gloade, who solely produced it.

The track by the 21-year-old Compton, California, native hits the Hot 100's summit in its fifth week on the chart, as it tallies a second week at No. 1 on the Streaming Songs survey, surging by 60% to 68.2 million U.S. streams in the week ending Jan. 9, according to Nielsen Music/MRC Data. Notably, the song does not yet have a proper official video; Its official audio clip was released on Dec. 6, while a new lyric video arrived on Jan. 9.

The streaming sum is the second-highest for any song, after Mariah Carey's "All I Want for Christmas Is You" drew 72.2 million (Jan. 4), since Lil Nas X's "Old Town Road," featuring Billy Ray Cyrus, hauled in 72.5 million (Aug. 3, 2019); "Road" set the record with 143 million on April 20, 2019.

"The Box" roars 31-8 on Digital Song Sales, up 79% to 11,000 sold in the week ending Jan. 9 (as it claims the Hot 100's top Streaming Gainer and Sales Gainer awards), and hikes by 196% to 10.9 million all-format radio airplay audience impressions.

The single concurrently crowns the Hot R&B/Hip-Hop Songs and Hot Rap Songs charts, which employ the same multi-metric methodology as the Hot 100, for a second week each.

"The Box" is from the rapper's debut studio album, Please Excuse Me for Being Antisocial, which began as his first No. 1 on the Billboard 200, dated Dec. 21 and this week (Jan. 18) rebounds for a second week on top. Roddy Ricch is the first artist to top the Hot 100 and Billboard 200 simultaneously since Lady Gaga and Bradley Cooper's "Shallow" and their soundtrack to A Star Is Born led the respective rankings dated March 9, 2019; As with Roddy Ricch, those titles brought actor/singer Cooper his first No. 1 on each chart.

Roddy Ricch further posts his second-highest Hot 100 rank, as Mustard's "Ballin'," on which he's featured, lifts 12-11, and he adds his fourth top 40 entry, as "High Fashion," featuring Mustard, flies 70-35 as it enters Streaming Songs at No. 12 (18.1 million, up 66%).

Justin Bieber's "Yummy" arrives at No. 2 on the Hot 100 as it starts at No. 1 on Digital Song Sales (71,000 sold in the week ending Jan. 9) and No. 2 on Streaming Songs (29.3 million in the same span), while soaring 38-10 on the Radio Songs chart (50.9 million in its first full week, ending Jan. 12).

As for the song's sales total, 71,000 marks the best since Taylor Swift's "You Need to Calm Down" launched with 79,000 (June 29, 2019).

"Yummy" was released at midnight ET on Jan. 3, while its official video premiered the following day. Its sales sum in the tracking week was boosted by a bevy of vinyl and cassette single offers in his official webstore (with certain pieces to be autographed by Bieber), and consumers received a digital copy of the song upon each purchase; Its airplay total includes hourly plays on participating Entercom Communications-owned radio stations on Jan. 11.

With "Yummy," Bieber banks his 17th Hot 100 top 10 (dating to his first, the No. 5-peaking "Baby," on Feb. 6, 2010), 14th Radio Songs top 10 and 11th Digital Song Sales No. 1, the lattermost total lifting him ahead of Drake and Eminem for the most among male artists. Bieber ties Katy Perry for the third-most Digital Song Sales leaders, after Swift (18) and Rihanna (14).

"Yummy" concurrently vaults from No. 16 to No. 1 on Hot R&B Songs, becoming Bieber's second topper on the tally (among eight top 10s), and first as a lead artist. He initially led as featured, with Chance the Rapper and Quavo, on DJ Khaled's "No Brainer," for six weeks in August-October 2018. "Yummy" enters Hot R&B/Hip-Hop Songs at No. 2, where Bieber adds his fourth top 10.

Post Malone's "Circles" drops to No. 3 on the Hot 100 after three nonconsecutive weeks at No. 1, as it tallies a fourth week atop Radio Songs, up by 1% to 101.3 million in audience.

Maroon 5's "Memories" descends to No. 4 on the Hot 100 from its No. 2 high, while Dan + Shay and Bieber's No. 4-peaking "10,000 Hours" climbs 9-5, as it tops Hot Country Songs for a 14th week. Thanks to "Yummy" and "Hours," Bieber is the first artist with two concurrent top five Hot 100 hits since Post Malone, whose "Goodbyes," featuring Young Thug, and "Circles" ranked at Nos. 3 and 4, respectively, on Sept. 21.

Rounding out the Hot 100's top 10, Lewis Capaldi's "Someone You Loved" backtracks 4-6, following its three-week command; Tones and I's "Dance Monkey" keeps at its No. 7 best; Lizzo's No. 3-peaking "Good as Hell" drops 6-8; Arizona Zervas' "Roxanne" retreats 5-9, after reaching No. 4, while boasting top Airplay Gainer honors (49.5 million, up 21%); and Selena Gomez's "Lose You to Love Me" holds at No. 10, after it led the Nov. 9 chart.

(Note that with this week's charts, dated Jan. 18, Billboard has streamlined the inclusion of YouTube user-generated content [UGC] for song charts that incorporate streaming data, including the Hot 100. As of this week, only streams of video clips that are termed to be "song-UGC" will be factored into such charts, while "non-song UGC" will be excluded; The main difference between the two is that song-UGC content comprises clips of extended length that prominently feature a song.

Further, for streaming-based charts, the Hot 100 and other multi-metric genre-specific "Hot"-named surveys, such as Hot R&B/Hip-Hop Songs, which employ the same streaming-, airplay- and sales-based methodology as the Hot 100, song-UGC content will now be weighted at the same level as programmed streams; It was previously weighted at the same level as ad-supported, on-demand streams. Additionally, paid/subscription video streams from YouTube and audio streams, such as on YouTube Music, have been isolated and will contribute at the same level as paid/subscription streams, the highest of the three contributing streaming levels.)
