While 'Rude' rules for a sixth week, Grande and Azalea infuse the top 10 with three hits apiece, including new top 10s 'Break Free' and 'Black Widow'

MAGIC!'s pop/reggae smash "Rude" leads the Billboard Hot 100 for a sixth week, narrowly fending off Meghan Trainor's "All About That Bass," which surges 4-2 and takes over atop the Streaming Songs chart. Plus, Ariana Grande's "Break Free" and Iggy Azalea's "Black Widow" soar into the top 10, granting both artists a rarity of three songs each in the region.
 
Meanwhile, get ready for Taylor Swift's new "Shake It Off" to challenge for the top spot on next week's Hot 100. (Read on …)

Let's dig right into the numbers behind a busy new Hot 100, as we do each Wednesday.

"Rude" again maintains its hold atop the Hot 100 despite not leading any of the chart's main component lists that rank airplay, sales and streaming. Even though it's not No. 1 in any main measurement, it continues to show strong numbers overall. "Rude" holds at No. 2 on Radio Songs (which it led for a week) with 161 million all-format audience impressions, down 3 percent, according to Nielsen BDS. It also keeps at No. 2 on On-Demand Songs (2.9 million, down 3 percent), which it led for three weeks. It drops from its No. 2 peak on Streaming Songs to No. 4 (7.7 million U.S. streams, down 7 percent) and falls 5-7 on Digital Songs with 104,000 downloads sold (down 15 percent) in the week ending Aug. 17, according to Nielsen SoundScan; it crowned Digital Songs for three weeks.
 
Trainor's "Bass" blasts 4-2 as the Hot 100's top Digital and Airplay Gainer and vaults 5-1 on Streaming Songs, up by 32 percent to 8.1 million. The newcomer's doo-wop/pop hit rules Digital Songs for a second week with 239,000 sold, up 21 percent. "Bass" extends its record for the most consecutive weeks winning the Digital Gainer award to five. In its second week on Radio Songs, the track charges 45-24 (47 million, up 64 percent).

With "Rude" down by 7 percent in overall Hot 100 points and "Bass" up by a hefty 29 percent, the latter should be ready to overtake the former next week. The uncertainty is whether Swift's "Shake" will bypass it and block it from the top. (Keep reading …)

Sam Smith's 'Stay' Hits No. 1 On Pop Songs

As "Bass" jumps, Sam Smith's "Stay With Me" dips to No. 3 after two weeks at its No. 2 Hot 100 high. It remains the most-heard song in the U.S. (in the week ending Aug. 19), logging a second week at No. 1 on Radio Songs (175 million, up 1 percent). "Stay" collects a third week atop On-Demand Songs (3.1 million, down 4 percent), while descending 4-5 on Digital Songs (105,000, down 15 percent; it led the list for two weeks last month) and 4-8 on Streaming Songs (6.1 million, down 3 percent).

Taylor Swift's 'Shake It Off' Set to Take Off on Hot 100

The most exciting action on next week's Hot 100 might belong to a song not yet on the chart: Swift's "Shake It Off." The song barely misses this week's list, fueled by its first two days of airplay; still, it enters Radio Songs at No. 45 with 29 million in all-format audience. Because the Hot 100's sales and streaming tracking weeks run Monday through Sunday, while airplay covers a Wednesday-Tuesday schedule, only the song's airplay counts toward this week's Hot 100; next week, once sales and streaming join the mix, "Shake" should battle for No. 1. With industry sources suggesting that the high-energy lead single from 1989 (due Oct. 27) could debut with 425,000-450,000 downloads sold, Swift could shake all the way to No. 1 next week.
 
We'll find out the next winner on the Hot 100 a week from today.
