As previously reported, Justin Bieber's "What Do You Mean?" vaults onto the Billboard Hot 100 (dated Sept. 19) at No. 1, marking his first leader and just the 23rd chart-topping debut in the list's history. Plus, Demi Lovato, Taylor Swift and Macklemore & Ryan Lewis all surge in the Hot 100's top 20, powered in large part (like Bieber) by appearances and/or performances at the MTV Video Music Awards Aug. 30.

Justin Bieber Scores First Hot 100 No. 1 With Debut of 'What Do You Mean?'

Oh, and The Weeknd boasts 10 songs on the Hot 100, becoming just the sixth act ever to claim that many titles on the tally simultaneously.

Want even more Hot 100 chart moves this week? We've got 'em.

Luke Bryan, "Strip It Down"

The second single from Bryan's Kill the Lights -- which has led Top Country Albums for each of its first four chart weeks (selling 496,000 copies to date, according to Nielsen Music) -- lifts 53-48 on the Hot 100. On Country Airplay, it jumps 13-8 to become his 19th top 10 and ties for his quickest climb to the tier: five weeks. 2013's "That My Kind of Night" also needed just five frames to reach the Country Airplay top 10.

Kelly also performed on the VMAs. The result? Her highest Hot 100 rank. After she sang "Should've Been Us" on the show, it bounds 75-51. She'd previously charted as high as No. 60 with her first hit, "Nobody Love," in May. "Us" soars by 117 percent to 49,000 downloads sold in the week ending Sept. 3, flying 49-19 on the Digital Songs chart.

Although the ballad dips from its No. 51 highpoint to No. 53 on the Hot 100 (but with a bullet), Trainor scores her fifth hit on the Pop Songs airplay chart, where the collab debuts at No. 39. All four singles from her first album Title have now reached Pop Songs, while Charlie Puth's "Marvin Gaye," featuring Trainor, holds at its No. 17 high.

There's also notable action for two independent releases on Pop Songs, from the bottom to the top (as Trainor would say). Teen singer Daya debuts at the airplay chart's No. 40 anchor spot with "Hide Away," released on indie label Artbeatz, while Major Lazer and DJ Snake's "Lean On" ft. MO (at No. 6 on the Hot 100 after reaching No. 4) tops Pop Songs (2-1). The coronation is a coup for independent Mad Decent. "Major labels still have the clout, but we have credibility, too," says Dale Connone, president of in2une Music, which has promoted "Lean" to radio. "This is a milestone."

Imagine Dragons, "Roots"

The stand-alone single (not from the group's recent album Smoke + Mirrors) enters the Hot 100 at No. 77 and crowns Rock Digital Songs (47,000) after its first full week. True to its title, Imagine Dragons promoted the song socially with childhood photos of the band members and fans.

Nicki Minaj, "The Night Is Still Young"

Another song fueled by the VMAs, the No. 31-peaking hit re-enters the Hot 100 at No. 98. It gains by 174 percent to 15,000 sold after she performed it with Swift at the festivities. Also part of her appearance, she sang fellow The Pinkprint track "Trini Dem Girls"; featuring Lunchmoney Lewis, it debuts at No. 33 on Billboard + Twitter Top Tracks.
