Bieber notches his second No. 1, unseating Adele's "Hello" after 10 weeks on top. Plus, his newest single "Love Yourself" takes over atop the Digital Songs chart.

It's not too late to say "Sorry" … is the No. 1 song on the Billboard Hot 100.

After eight total, and seven consecutive, weeks at No. 2, Justin Bieber's "Sorry" crowns the Hot 100 (dated Jan. 23) at last. The track dethrones Adele's "Hello," which had spent its first 10 weeks at No. 1 dating to its debut atop the Nov. 14 chart; "Sorry" debuted the same week at No. 2.

"Sorry," released on SchoolBoy/Raymond Braun/Def Jam, marks Bieber's second Hot 100 No. 1, and second-in-a-row, after a lengthy wait for his first topper. After six years of charting 46 prior entries, beginning in July 2009, Bieber earned his first No. 1 on the Hot 100 dated Sept. 19, when "What Do You Mean?" debuted at No. 1. Now, he's achieved two leaders back-to-back.

As we do every Monday, let's run down the Hot 100's top 10, and beyond. Highlights of the airplay/sales/streaming-based Hot 100 post on Billboard.com each Monday, with all charts updated each Tuesday.

"Sorry" (the 1,049th No. 1 in the Hot 100's 57-year history) notches a fourth week at No. 1 on the Streaming Songs chart with 20 million U.S. streams, down 14 percent, and leads the subscription services-based On-Demand Songs chart for an eighth week (8.5 million on-demand streams, down 10 percent), according to Nielsen Music. It holds at its No. 2 high (for a fifth week) on Radio Songs (145 million audience impressions, up 6 percent), while dropping 2-3 on Digital Songs (128,000 downloads sold, down 53 percent, in the week ending Jan. 7); it led the sales list for a week in December. (Most songs declined in sales in the tracking week, following the robust frame ending Dec. 31, in which many consumers surely redeemed gift cards received as holiday presents.)

Three more fun facts regarding Bieber's Hot 100 takeover:

Longest wait at No. 2: With its eight total weeks at No. 2 before hitting No. 1 on the Hot 100, "Sorry" ties for the most weeks spent at the runner-up spot before reaching the summit. OutKast's "The Way You Move" (featuring Sleepy Brown) also waited at No. 2 for eight frames, all in-a-row, in 2003-04. Then again, the hip-hop duo surely didn't mind so much, as its own "Hey Ya!" ruled the list during all those weeks. (Only one other song, in addition to "Sorry," has waited at No. 2 for exactly seven consecutive weeks before crowning the Hot 100: LMFAO's "Sexy and I Know It" in 2011.)

So "Sorry": Bieber brings the word "Sorry" to the top of the Hot 100 for the fourth time (and first in the 21-year-old's lifetime). The prior three leaders with "Sorry" in their titles: Brenda Lee's "I'm Sorry" (1960); John Denver's "I'm Sorry" (not the same composition as Lee's) (1975); and Chicago's "Hard to Say I'm Sorry" (1982).

Ruling rhythmic radio: "Sorry" also hits No. 1 (2-1) on Billboard's Rhythmic Songs radio airplay chart. It's his second leader on the format ranking, following 2012's "As Long as You Love Me" (featuring Big Sean).

That's not all the good news for Bieber this week: he additionally ranks at No. 3 on the Hot 100 as newest single "Love Yourself" stays at its peak, while taking over atop Digital Songs (3-1; 164,000, down 39 percent). It keeps at No. 3 on Streaming Songs (15.1 million, down 4 percent) and climbs 16-12 on Radio Songs (73 million, up 39 percent) (good for the Hot 100's top Airplay Gainer award).

Bieber again places three songs in the Hot 100's top 10, as "Mean" drops 5-8. "Sorry," "Love Yourself" and "Mean" are all from his album Purpose, which bowed atop the Dec. 5 Billboard 200 (becoming his sixth No. 1). The set holds at No. 2 this week and has sold 1.3 million copies in its first eight weeks.

As Bieber bounds to No. 1 on the Hot 100, Adele's "Hello," the lead single from her album 25, drops to No. 2 after logging its first 10 weeks at No. 1. Still, it tallies a ninth week (extending Adele's longest command on the chart) at No. 1 on Radio Songs (169 million, down 2 percent). The ballad falls 1-2 after seven weeks atop Digital Songs (139,000, down 58 percent) and keeps at No. 2 on Streaming Songs (where it also notched seven weeks at No. 1) with 16.3 million U.S. streams, down 18 percent.

Meanwhile, second 25 single "When We Were Young" rises 47-41 on the Hot 100. 25 tops the Billboard 200 for a seventh week (encompassing its entire run) and has sold 7.6 million to date.

The race for No. 1 on the Hot 100 was quite close again this week, with "Sorry" finally finishing ahead of "Hello": while both songs declined sharply in overall activity thanks to the hefty decline in sales for most songs in the tracking week, "Sorry" slipped by 24 percent in Hot 100 chart points, while "Hello" fell by 31 percent.

As for non-Bieber/Adele news in the Hot 100's top five: Drake's "Hotline Bling" holds at No. 4, after reaching No. 2 (and dominates Billboard's Hot R&B/Hip-Hop Songs chart for an 11th week and Hot Rap Songs for a 16th frame), and Twenty One Pilots land their first top five hit, as "Stressed Out" flies 9-5. The latter single stays at No. 4 on Digital Songs (116,000 sold, down 27 percent) and rises 12-11 on Radio Songs (75 million, up 27 percent) and 20-13 on Streaming Songs (7.9 million, up 10 percent). "Stressed Out" concurrently leads the Hot Rock Songs chart for a third week.

Rounding out the Hot 100's top 10, Selena Gomez's "Same Old Love" returns to its best rank (7-6) and, as previously reported, hits No. 1 on the Pop Songs airplay chart; Shawn Mendes' "Stitches" slips 6-7 (after peaking at No. 4); and, below Bieber's "Mean" at No. 8, Alessia Cara's debut hit "Here" drops 8-9 (after reaching No. 7) and Meghan Trainor's "Like I'm Gonna Lose You," featuring John Legend, remains at No. 10 after rising to No. 8. As previously reported, "Like" takes over atop the Adult Pop Songs airplay chart.

Among noteworthy action outside the Hot 100's top 10, Drake and Future's "Jumpman" rises 13-12, returning to its peak; The Chainsmokers' "Roses," featuring ROZES, roars 22-13, marking the duo's highest-peaking Hot 100 hit (its debut, "#SELFIE," reached No. 16 in April 2014. "Roses" also rules the Hot Dance/Electronic Songs chart for a third week); and, Post Malone's "White Iverson" jumps 15-14.
