The Canadian quartet rules for a fifth week with 'Rude,' while Trainor's 'All About That Bass' bounds and Charli XCX's 'Boom Clap' enters the top 10.

MAGIC!'s "Rude" rules the Billboard Hot 100 for a fifth week. Meanwhile, Meghan Trainor's "All About That Bass" jumps 8-4, while taking over atop the Digital Songs chart, and Charli XCX charges into the Hot 100's top 10 with "Boom Clap." Plus, Sam Smith's "Stay With Me" rises to the top of the Radio Songs chart.



Wednesday always means a new Hot 100, so let's dive into the numbers behind the latest top 10.





"Rude" maintains its hold atop the Hot 100 despite not leading any of the chart's main component surveys that rank airplay, sales and streaming. (It's a fairly rare occurrence, as, in the 83 weeks dating back to the debut of the Streaming Songs survey early last year, the top Hot 100 title hasn't led Radio Songs, Digital Songs or Streaming Songs, nor the subscription services-based On-Demand Songs chart, in only seven of those frames.)



How does "Rude" continue to dominate? Even though it's not No. 1 in any main metric, it's still showing strong numbers in all. It falls 1-2 on Radio Songs after a week at the summit (166 million all-format audience impressions, down 2 percent, according to Nielsen BDS). It holds at its No. 2 high on Streaming Songs (8.2 million U.S. streams, up 2 percent) and stays at No. 2 on On-Demand Songs (3 million, down 5 percent), which it led for three weeks. On Digital Songs, "Rude" keeps at No. 5 with 122,000 downloads sold (down 8 percent) in the week ending Aug. 10, according to Nielsen SoundScan. It topped the chart for three weeks.

Sam Smith Settles In For A No. 1 'Stay' On Adult Contemporary

Sam Smith's "Stay With Me" logs a second week at its No. 2 high on the Hot 100 and becomes the most-heard song in the U.S. (in the week ending Aug. 12), rising 2-1 on Radio Songs (173 million, up 6 percent). "Stay" stays at No. 1 on On-Demand Songs, where it reigns for a second week (3.2 million, down 3 percent), and No. 4 on both Digital Songs (123,000, down 11 percent; it led the list for two weeks last month) and Streaming Songs (6.3 million, up 2 percent).



MAGIC! wins a close race over Smith for the Hot 100's top spot, thanks to its slight lead in overall streaming, since the latter finishes ahead in both airplay and sales. "Rude" is 6 percent in front of "Stay" in overall Hot 100 points, narrowing the gap from 9 percent last week and likely setting up another spirited battle next week.



Iggy Azalea's former seven-week No. 1 "Fancy," featuring Charli XCX (more about her own latest achievement ahead …), remains at No. 3 on the Hot 100. As it leads Streaming Songs for a 13th week (8.9 million, up 3 percent), it ties Miley Cyrus' "Wrecking Ball" for the most weeks tallied at No. 1. "Fancy" also tops Hot Rap Songs for a 17th week and Hot R&B/Hip-Hop Songs for a 12th frame. It dominates the Songs of the Summer chart for an 11th week, continuing as the only title that's led the seasonal list since it made its annual return after Memorial Day.





The M-Train (aka, Meghan Trainor, to borrow her self-appointed handle) keeps on rollin', as "All About That Bass" blasts 8-4 on the Hot 100 and is the new No. 1 (2-1) on Digital Songs. It tops the latter chart with a 17 percent jump to 197,000 sold, good for top Digital Gainer honors for a fourth straight week. How notable is that streak? "Bass" is the first song to earn the award for four consecutive weeks since digital sales began contributing to the Hot 100 in February 2005. Prior to the digital era, the Hot 100 bestowed a top "Sales Gainer" honor (powered by physical singles' increases), and the last time a song took that title for four weeks in a row was more than 10 years ago: JoJo's fellow debut hit "Leave (Get Out)" in May 2004. (Must be something special in the Massachusetts air: JoJo, while born in Vermont, was raised in Foxborough, Mass. Trainor is from the state's island of Nantucket.)

Meghan Trainor On 'All About That Bass': It's About 'Loving Your Body … And Your Booty'

Sales account for the majority (55 percent) of the Hot 100 chart points for "Bass," but it's surging across-the-board, also claiming top Streaming Gainer kudos for a second straight week and leaping 13-5 on Streaming Songs (6.2 million, up 47 percent). It debuts on Radio Songs at No. 45, up by 59 percent to 29 million.



Nico & Vinz's "Am I Wrong" retreats from its Hot 100 peak (4-5), while Ariana Grande's "Problem," featuring Azalea, dips 5-6 after peaking at No. 2 for five weeks.



Maroon 5's "Maps" holds at its Hot 100 highpoint (7-7), while Sia's "Chandelier" reaches a new best rank (9-8).





After debuting last week at No. 6, Jessie J, Grande and Nicki Minaj slip to No. 9 with "Bang Bang." Download sales continue to contribute the biggest bulk of its chart points (52 percent), with 141,000 sold (down 39 percent). It drops 1-2 on Digital Songs, but powers 21-14 on Streaming Songs (4.1 million, up 34 percent) and 47-37 on Radio Songs (38 million, also up 34 percent).



Rounding out the Hot 100's top 10, Charli XCX's "Boom Clap" thunders 11-10 as the top Airplay Gainer. The track, from the soundtrack to "The Fault in Our Stars," lifts 10-8 on Radio Songs, up by 19 percent to 83 million. It holds at No. 11 on Digital Songs (87,000, down 6 percent) and No. 20 on Streaming Songs (3.5 million, up 3 percent). The British singer/songwriter scores her third top 10 in as many Hot 100 visits, and, notably, her first in a lead role. Prior to the seven-week reign of "Fancy," she reached No. 7 last year as featured on Icona Pop's "I Love It."



Disclosure's "Latch," featuring Smith, departs the Hot 100's top 10, falling 10-11, but commands the Hot Dance/Electronic Songs chart for a fifth week.



Also just below the Hot 100's top 10, Minaj's "Anaconda" slithers in as the top debut at No. 19. Sales lead the way (accounting for 71 percent of its overall points), as the cut launches at No. 3 on Digital Songs with 141,000. The song is Minaj's 51st Hot 100 hit, extending her mark for the most among female rappers (Missy Elliott is next with 31) and tying her with Eminem for the seventh-best total among all rappers; Lil Wayne leads the category with 122. Among all artists, Minaj breaks out of a tie with Michael Jackson and also equals Rod Stewart's 51 career Hot 100 entries.
