With 'Sorry' at No. 2 and prior hit 'What Do You Mean?' at No. 5, Biebs boasts simultaneous top five hits. Plus, Taylor Swift tallies a fourth Radio Songs No. 1 from '1989' with 'Wildest Dreams.'

As reported, Adele's "Hello" rockets onto the Billboard Hot 100 (dated Nov. 14) at No. 1, setting a record for the most downloads sold in a week: 1.11 million, according to Nielsen Music.

Adele Says 'Hello' to No. 1 Hot 100 Debut & 1-Million-Plus Sales Record

That's far from the only action in the Hot 100's upper reaches, as Justin Bieber's "Sorry" starts at No. 2. Plus, Taylor Swift collects a fourth No. 1 on the Radio Songs chart with "Wildest Dreams."

As we do each Monday, let's run down the Hot 100's top 10 and more (on the chart dated Nov. 14). Highlights of the airplay/sales/streaming-based Hot 100 post on Billboard.com each Monday, with all charts updated each Tuesday.

"Sorry" starts at No. 2 on the Hot 100, Digital Songs and Streaming Songs charts. It launches with 277,000 downloads sold in the week ending Oct. 29, according to Nielsen Music, and 23.1 million U.S. streams. It enters Radio Songs at No. 37 with 34 million in all-format audience (up 99 percent in its first full week of airplay).

A few key stats regarding Bieber's No. 2 debut:

Two No. 1 Hot 100 debuts in same week: With Adele arriving at No. 1 with "Hello" and Bieber bowing at No. 2 with "Sorry," the Hot 100 welcomes debuts in the first two spots for only the second time in the chart's 57-year history. On the June 28, 2003, chart, Clay Aiken's "This Is the Night" and Ruben Studdard's "Flying Without Wings" landed at Nos. 1 and 2, respectively, in their first weeks. Aiken and Studdard, of course, finished in reverse order in the 2003 season of Fox's American Idol; the songs were recorded as each's potential coronation single ahead of the season finale and made available for purchase following the episode.

Thus, while Adele and Bieber bring the second pair of simultaneous debuts at Nos. 1 and 2 on the Hot 100, "Hello" and "Sorry" mark the first set of Nos. 1 and 2 starters not so obviously related, a la Aiken and Studdard's Idol connection. Adele and Bieber's singles arrive adjacent more coincidentally (perhaps linked most closely by their shared apologetic lyrical themes).

Two top two debuts from same album: With Bieber having debuted at No. 1 on the Hot 100 with prior single "What Do You Mean?" (Sept. 19), "Sorry" (his eighth Hot 100 top 10) is the second song from his Nov. 13 album Purpose to start at No. 1 or 2. Only three other albums have yielded multiple singles that have entered the Hot 100 so high: Mariah Carey's Daydream (1995-96) and Butterfly (1997-98) and Eminem's Recovery (2010). Daydream generated the No. 1 beginners "Fantasy" and "One Sweet Day" (with Boyz II Men) and the No. 2 opener "Always Be My Baby" (which went on to hit the summit), while Butterfly spun off the No. 1 debut "Honey" and No. 2-starting (and No. 1-peaking) "My All." Recovery produced the No. 1-debuting "Not Afraid" and "Love the Way You Lie" (featuring Rihanna), which launched at No. 2 before rising to No. 1.

Two in top five: Meanwhile, "Mean" remains in the Hot 100's top five, dipping 3-5. Bieber is the 20th solo male to double up in the top five, a list that started with Elvis Presley in 1959. (50 Cent holds the record among solo males, with three simultaneous top five Hot 100 hits for two weeks in 2005. He and the Beatles, with a clean-sweep record five on April 4, 1964, are the only acts to have logged at least three concurrent top five tracks.)

Beneath "Hello" and "Sorry" and above "Mean" on the Hot 100, Drake's "Hotline Bling" drops to No. 3 after three weeks at its No. 2 high, and perhaps overshadowed by Adele and Bieber's debuts, The Weeknd's "The Hills" falls to No. 4 after six nonconsecutive weeks on top. "Bling" replaces "Hills" atop Hot R&B/Hip-Hop Songs, becoming Drake's lucky 13th No. 1 on the genre chart. "Bling" tallies a sixth week atop Hot Rap Songs, where it's Drake's record 15th No. 1. "Hills" leads the Hot R&B Songs chart for a seventh week.

Shawn Mendes' "Stitches" slips to No. 6 on the Hot 100 from its No. 4 peak, while Taylor Swift's "Wildest Dreams" drops to No. 7 from its No. 5 highpoint. Still, Swift adds a new honor with the song: "Dreams" darts 2-1 on Radio Songs (150 million, up 2 percent), becoming her fourth No. 1 from her album 1989 and her sixth Radio Songs leader overall. Swift previously topped the chart with 1989 singles "Shake It Off" (for four weeks), "Blank Space" (six) and "Bad Blood," featuring Kendrick Lamar (five). Her first two Radio Songs No. 1s: "You Belong With Me," for two weeks in 2009 (from Fearless), and "I Knew You Were Trouble." (four, 2013, from Red).

Rihanna boasts the most Radio Songs No. 1s (12), dating to the chart's 1990 origin, while Katy Perry has notched the most leaders from one album: five, from Teenage Dream (2010-11).

Rounding out the Hot 100's top 10, Fetty Wap's "679," featuring Remy Boyz, slides 6-8 after reaching No. 4; R. City's No. 6-peaking "Locked Away," featuring Maroon 5's Adam Levine, descends 8-9; and The Weeknd's former three-week Hot 100 No. 1 "Can't Feel My Face" falls 7-10.

Among action outside the Hot 100's top 10, Elle King's "Ex's & Oh's" rises to a new peak (15-12); Meghan Trainor's "Like I'm Gonna Lose You," featuring John Legend, leaps 18-13, also reaching a new best rank; and, Alessia Cara's breakthrough hit "Here" likewise charts new territory (20-15).
