Bruno Mars Still Atop Hot 100, & Britney Spears Enter Top 10

With five weeks on top, 'Locked Out of Heaven' becomes Mars' longest-leading No. 1.

Bruno Mars remains atop the Billboard Hot 100, as "Locked Out of Heaven" logs a fifth week at No. 1. and Britney Spears' "Scream & Shout," meanwhile, enters the top 10 and Macklemore & Ryan Lewis' "Thrift Shop," featuring Wanz, crowns the On-Demand Songs chart.

With a fifth frame atop the Hot 100, "Heaven" becomes the longest-reigning of Mars' four No. 1s. He first led for two weeks as a guest on B.o.B's "Nothin' On You" (2010). He then rang up twin four-week commands with his own "Just the Way You Are" (2010) and "Grenade" (2011).

As it maintains its rule over the Hot 100, "Heaven" spends a third week at No. 1 on the Hot 100 Airplay chart, posting a 6% increase to 149 million all-format audience impressions, according to Nielsen BDS. "Heaven" holds at No. 2 on On-Demand Songs, gaining by 3% to 1.05 million on-demand streams, according to BDS. It dips 2-3 on Hot Digital Songs, down by 53% to 233,000 downloads sold, according to Nielsen SoundScan. (As previously reported, most songs experience sharp declines in digital sales following the end of the robust holiday shopping period, which included consumers cashing in online music retailer gift cards.)

Rihanna's former three-week Hot 100 No. 1 "Diamonds," atop Hot R&B/Hip-Hop Songs for a 14th week, rebounds 3-2 on the Hot 100. It holds at No. 2 on Hot 100 Airplay (132 million, down less than 1%), falls 1-3 after six nonconsecutive weeks atop On-Demand Songs with 1.04 million on-demand streams (down 2%) and slides 5-9 on Hot Digital Songs (160,000, down 56%).

"Heaven" sports a lead of approximately 8,000 overall Hot 100 chart points over "Diamonds," although each title drops by 31%. Much closer is the race between the songs at Nos. 2-4, which are separated by only about 1,000 chart points.

After bounding 4-2 last week, Taylor Swift's "Trouble" retreats 2-3, although it claims the Hot 100's top Airplay Gainer award. The cut roars 12-7 on Hot 100 Airplay with a 21% surge to 81 million, becoming her sixth top 10 on the tally (and second in a row, following the No. 3-peaking Hot 100 Airplay hit, and Hot 100 No. 1, "We Are Never Getting Back Together.") "Trouble" spends a third nonconsecutive week atop Hot Digital Songs (326,000, down 44%). The song is not available to subscription streaming services and, thus, does not rank on On-Demand Songs.

The Lumineers' "Ho Hey" stays at No. 4 on the Hot 100, while leading the Hot Rock Songs chart for an eighth week. It keeps at No. 3 on Hot 100 Airplay (1.16 million, up 8%), rises 5-4 on On-Demand Songs (924,000, up 16%) and backtracks 6-7 on Hot Digital Songs (186,000, down 39%).

Macklemore & Lewis' "Thrift Shop" soars 10-5 with the Hot 100's top Streaming Gainer tag. After the pair's independently-released album "The Heist" blasted onto the Billboard 200 at No. 2 the week of Oct. 27, the track reaches the top of On-Demand Songs, where it jumps 3-1 with 1.12 million on-demand streams, (up 20%). (It registers 1.26 million overall streams.) "Thrift" charges 7-2 on Hot Digital Songs (236,000, down 22%) and 51-38 on Hot 100 Airplay (33 million, up 26%). The rap track is earning support at a variety of formats, ranking at No. 14 on Rhythmic, No. 17 on Alternative and No. 25 on Mainstream Top 40.

Phillip Phillips' "Home" reaches a new peak, No. 6, up from No. 9, in its 28th week on the Hot 100 and Justin Bieber's "Beauty and a Beat," featuring Nicki Minaj, slips from its No. 5 peak to No. 7.

After five weeks between Nos. 12 and 15, the superstar pairing of and Britney Spears results in a top 10 rank at last, as "Scream & Shout" storms 12-8 on the Hot 100. The duet pushes 9-4 on Hot Digital Songs (203,000, down 29%) and passes 1 million sold to date. It rises 16-11 on On-Demand Songs (668,000, up 26%) and 27-21 on Hot 100 Airplay (46 million, up 21%).

With the song's ascent, scores his third solo top 10 and first as a lead artist. He'd reached the top tier as a guest on Flo Rida's No. 9-peaking "In the Ayer" (2008) and Usher's four-week No. 1 "OMG" (2010). He's added 10 top 10s as a member of the Black Eyed Peas for a total of 13 top 10 visits overall. 2013 also brings the lucky 13th top 10 appearance for Spears. She first reached the region the week of Dec. 12, 1998, when her debut single and first of five Hot 100 No. 1s, "...Baby One More Time," climbed 18-9. She'd last populated the top 10 with the No. 7-peaking "I Wanna Go" in summer 2011.

Rounding out the Hot 100's top 10, Maroon 5's former nine-week No. 1 "One More Night" descends 8-9 and Flo Rida's No. 6-peaking "I Cry" returns to the upper bracket (11-10).
