As previously reported, Katy Perry's "Dark Horse," featuring Juicy J, spends a third week at No. 1 on the Billboard Hot 100 and Pharrell's "Happy" jumps 8-2. Who else makes notable moves on Billboard song charts this week?
-- Katy Perry: First, two more nuggets about Perry this week. She ties the record for the most No. 1s in the 21-year history of the Mainstream Top 40 radio airplay chart, where "Dark Horse" trots 3-1. The song marks Perry's 11th No. 1 on the ranking, equaling Rihanna's sum. Rihanna had pulled ahead of Perry when Eminem's "The Monster," on which Rihanna is featured, began a five-week reign the week of Dec. 21.
Perry also scores her 13th consecutive (and overall) No. 1 on Dance Club Songs with "Horse," courtesy of remixes from Goldhouse, Manhattan Clique, Country Club Martini Crew and 4FRNT, among others. Perry extends her record for the most leaders in a row since the chart's Aug. 28, 1976, inception as a national survey. The streak, which began with "Waking Up in Vegas" in August 2009, includes all of Perry's chart hits after her first two, 2008's "I Kissed a Girl" (No. 25 peak) and "Hot N Cold" (No. 32).
-- Ellie Goulding: She collects her second No. 1 on Dance/Mix Show Airplay, as "Burn" climbs 2-1. (It's up 16-14 on the Hot 100.) Goulding previously led the radio survey for two weeks in September 2012 with her breakthrough smash "Lights."
-- Aloe Blacc: As it rises 21-17 on the Hot 100, "The Man" opens on Hot R&B/Hip-Hop Songs at No. 6. The second single off his "Wake Me Up" EP was activated to coincide with its No. 47 opening on the Mainstream R&B/Hip-Hop airplay chart. In the Feb. 3-9 Nielsen BDS tracking week, it rose 25% to reach 3 million listeners at the format. "The Man" also debuts at No. 3 on R&B/Hip-Hop Digital Songs with 125,000 downloads, according to Nielsen SoundScan.
-- Avicii: The DJ becomes the first act in the relatively short 13-month history of Billboard's Hot Dance/Electronic Songs chart to occupy the top two positions, as "Wake Me Up!" enjoys a record-extending 23rd week at No. 1 and "Hey Brother" rises 4-2. The latter track claims Digital Gainer honors, as it shifts 63,000 downloads (up 8%). "Brother" also edges up Dance/Electronic Digital Songs (3-2) and Dance Club Songs (6-3), while "Wake" (at No. 19 on the Hot 100) returns for an 11th week at No. 1 on Dance Streaming Songs (2-1; 2.5 million U.S. streams, according to BDS).
-- Demi Lovato: "Neon Lights," up 64-46 on the Hot 100, arrives as the highest new entry on Digital Songs (No. 30, 51,000). Aiding its profile, on Feb. 5, Lovato released a teaser video on Twitter of her Neon Lights Tour, four days ahead of its kickoff in Vancouver.
-- Blake Shelton: He scores his 18th top 10 on Hot Country Songs with "Doin' What She Likes," which rises 12-9 (and 63-55 on the Hot 100). Shelton's Hot Country Songs history includes 12 No. 1s, a position he last attained with "Sure Be Cool If You Did," which spent five weeks on top a year ago.
-- Jhene Aiko: The singer, who enjoyed exposure (with Drake) on NBC's "Saturday Night Live" on Jan. 18, makes her Hot 100 debut with "The Worst" (No. 87), with the song sporting a fairly equal mix of airplay, sales and streaming. The sultry ballad jumps 28-25 on Hot R&B/Hip-Hop Songs and 38-31 on Rhythmic.
-- Christina Perri: After scoring hits with "Jar of Hearts" (No. 17) and "A Thousand Years" (No. 31) in 2011-12, the pop singer/songwriter returns to the Hot 100 at No. 90 with "Human," the first single from her second album, Head or Heart, due April 1. On Adult Top 40 (20-19), it's her fifth top 20 hit in as many tries.
-- U2: The band claims the Hot Rock Songs Hot Shot Debut with "Invisible" at No. 15. The charity single enters Rock Digital Songs at No. 11 with 26,000 downloads sold, a sum that accounts for 86% of its Hot Rock Songs points. Still, the song is off to a strong start at radio, as it storms Alternative at No. 28 (marking the band's best bow since "Get On Your Boots" launched at No. 8 five years ago). With the arrival, U2 reclaims the record for the most Alternative appearances (39) over Pearl Jam (38), dating to the chart's Sept. 10, 1988, inception. Green Day and Red Hot Chili Peppers follow with 30 entries each.
-- Yandel: He makes it three straight No. 1s on Latin Airplay, as "Hasta Abajo" leaps 6-1. The string began with his featured turn on Gocho's "Amor Real" (2012) and his own "Hable De Ti," which spent a week at No. 1 in October. "Abajo" recorded 12 million audience impressions, up 40%, last week and earns Airplay Gainer honors on Hot Latin Songs where it hops 11-9, marking his third solo top 10; he boasts an additional 21 Hot Latin Songs top 10s as half of Wisin & Yandel.
-- Club Nouveau: The group resumes its Billboard chart history, as the independently-released "That Ain't Love" debuts on Adult R&B at No. 27. The group had last graced a survey in 1998. Club Nouveau arrived with four consecutive Hot R&B/Hip-Hop Songs top 10s in 1986-87, including the No. 2-peaking "Lean on Me." The song topped the Billboard Hot 100 for two weeks in March 1987 and won a Grammy Award for best R&B song (for its writer, Bill Withers). With Withers' original version having crowned the Hot 100 for three weeks in 1972, "Lean" is one of nine songs to rule the chart by two different artists.
