As always, let's dig deeper into the numbers behind the Hot 100's top 10.
Rihanna's 13th No. 1 and Eminem's fifth leader holds at the Hot 100's summit, posting a fourth week atop the Radio Songs airplay chart. It slips by 7% to 136 million in all-format audience impressions, according to Nielsen BDS. On Digital Songs, which it led for three weeks, "Monster" rebounds 3-2 with 433,000 downloads sold (up 124%), according to Nielsen SoundScan; all titles on the 50-position Digital Songs chart gain this week, as consumers redeemed digital gift cards after Christmas. (Total digital song sales rise by 98% from the previous week.) "Monster" falls to No. 2 after a week atop Streaming Songs (4.7 million U.S. streams, down 38%, according to BDS) and drops 1-2 after six weeks at No. 1 on the subscription services-based On-Demand Songs chart (1.6 million, down 25%).
As "Monster" marks four weeks atop the Hot 100, Rihanna collects her 51st career week at the summit, pushing her past Boyz II Men (50 weeks) for the third-most weeks spent at No. 1 in the chart's 55-year history. Mariah Carey leads with 79 total weeks at No. 1 (via 18 toppers), followed by the Beatles (59 frames from 20 No. 1s). Usher rounds out the top five with 47 weeks at No. 1, thanks to nine leaders.
"Monster" spends a ninth week at No. 1 on both the Hot R&B/Hip-Hop Songs and Rap Songs charts. It leads the Rhythmic radio-based list for a fifth week and Pop Songs and Rap Airplay for a fourth week each.
The song holds off Pitbull's "Timber," featuring Ke$ha, for a fourth week. "Timber" returns for a third week atop Digital Songs (2-1; 442,000, up 108%), but descends 4-6 on Streaming Songs (4.4 million, down 15%) and 5-6 on Radio Songs (100 million, down 3%).
While Eminem and Rihanna maintain their lead on the Hot 100, Pitbull and Ke$ha climb closer in overall chart points. A week ago, a 17% difference in points separated the songs. This week, with "Monster" up by 31% and "Timber," 46%, the margin shrinks to 6%, the closest between the songs yet.
The Hot 100's top three songs remain in place from last week, with OneRepublic's "Counting Stars" at No. 3 for a fourth frame, adding Digital Gainer honors. "Stars" shoots 4-3 on Digital Songs (408,000, up 143%), holds at No. 2 on Radio Songs for a third week (131 million, down 1%) and dips 7-10 on Streaming Songs (3.8 million, down 16%).
Lorde's former nine-week Hot 100 No. 1 "Royals" rises 5-4 (and leads Hot Rock Songs for an 18th week), swapping spots with A Great Big World and Christina Aguilera's "Say Something" (4-5). Still, the latter title lifts 16-14 on Radio Songs (54 million, up 8%) and gains by 49% to 355,000 downloads, despite falling 1-4 on Digital Songs. On Streaming Songs, "Something" slides 6-11 (3.6 million, down 22%).
Imagine Dragons' "Demons" stays at its No. 6 Hot 100 peak, while Passenger's "Let Her Go" likewise holds at its No. 7 highpoint.
Katy Perry returns to the Hot 100's top 10 with her former two-week No. 1 "Roar" (11-8), which claims top Airplay Gainer accolades, rebounding 13-10 on Radio Songs (64 million, up 18%). The song is one of several 2013 smashes that gain in airplay, benefitting from spins on stations' year-end countdowns and retrospectives. Also resurging on Radio Songs: Robin Thicke's "Blurred Lines," featuring T.I. and Pharrell (25-18), Capital Cities' "Safe and Sound" (39-27) and Imagine Dragons' "Radioactive" (a re-entry at No. 46).
Rounding out the Hot 100's top 10, One Direction's No. 6-peaking "Story of My Life" rises 10-9 and Avicii's No. 4 hit "Wake Me Up!" tumbles 8-10. The latter track tops Dance/Electronic Songs for a record-extending 17th week.
Outside the Hot 100's top tier, Miley Cyrus soars with her new single, "Adore You," which re-enters at No. 22. (It first spent two sales-fueled weeks on the chart, at Nos. 42 and 79 in October/November, coinciding with the first two chart weeks of Billboard 200-topping parent album "Bangerz.") With its sensual video having premiered on YouTube Dec. 26 (a day after it leaked online), "Adore" rockets onto Streaming Songs at No. 1 with 7 million U.S. streams, 82% of which stem from Vevo on YouTube views. Since the chart launched the week of Jan. 26, 2013, just three other songs have started at the top: Baauer's "Harlem Shake," PSY's "Gentleman" and Lady Gaga's "Dope."
Cyrus also ranks at No. 2 on Streaming Songs with "Wrecking Ball" (6.9 million, up 8%), becoming the second act to monopolize the chart's top two. Macklemore and Ryan Lewis doubled up at Nos. 1 and 2 the weeks of May 11 and 18 with "Thrift Shop" and "Can't Hold Us," respectively. She's additionally the first artist to collect three No. 1s on Streaming Songs (passing PSY, with two). "We Can't Stop" and "Ball" share the record for the longest stays atop the chart: 11 weeks each. On the Hot 100, "Ball" drops (fittingly, this New Year's week) 9-12.
