As previously reported, "Harlem Shake," the viral smash from Baauer, logs a fourth week at No. 1 on the Billboard Hot 100, and Macklemore & Ryan Lewis' former four-week Hot 100 No. 1 "Thrift Shop," featuring Wanz, reaches No. 1 on Hot 100 Airplay. Who are other movers and … shakers … on the Hot 100 and other song charts this week?
-- P!nk:

Just outside the Hot 100's top tier, she roars 47-18 with Digital Gainer honors for "Just Give Me a Reason," featuring fun.'s Nate Ruess. The third single from her first Billboard 200 No. 1 album, "The Truth About Love," soars 25-8 on Hot Digital Songs (122,000 downloads sold, up 91%, according to Nielsen SoundScan), marking her ninth top 10 on the chart; enters Streaming Songs at No. 42 (1.1 million streams, up 33%), according to Nielsen BDS); and bounds 65-44 on Hot 100 Airplay (27 million, up 72%).
She began her Truth About Love tour on Feb. 13, likely helping spur the song's across-the-board growth. She moves on to Philadelphia and New York next week before playing in Dublin on April 12, kicking off a month-long European leg of the tour.

-- Demi Lovato: After "Heart Attack" blasted in as the Hot 100's top debut at No. 12 last week, largely owed to first-week sales of 215,000, the song stumbles to No. 22. But, the decline is typical of songs that make first-week splashes due to primarily sales. Don't be fooled, as its radio life is off to a strong chart, while its sales could rebound as the track builds overall familiarity. "Heart" falls 4-10 on Hot Digital Songs (107,000, down 50%) but leaps 70-49 on Hot 100 Airplay (25 million, up 73%) and arrives on Streaming Songs as the chart's highest new entry at No. 31 (1.3 million, up 38%).
The song previews her forthcoming fourth album.

-- Justin Timberlake: The rebound of "Mirrors" reflects the buzz of his double duties as host and musical guest on NBC's "Saturday Night Live" (March 9), as the cut jumps 97-77 on the Hot 100 and re-enters Hot Digital Songs at No. 48 (40,000, up 79%). His No. 4-peaking "Suit & Tie," featuring Jay-Z, meanwhile, returns to the Hot 100's top five (8-5) for the first time in almost two months (151,000, up 7%). Both songs introduce his highly-anticipated third solo set "The 20/20 Experience," due Tuesday (March 19).

-- Anna Kendrick:

Released in its original a capella form on the "Pitch Perfect" soundtrack, "Cups" (85-85 on the Hot 100), from the film's star, is earning mainstream top 40 radio support thanks to a new edit featuring instrumentation. KZHT Salt Lake City leads with 48 plays for it last week.

-- Phillip Phillips: The reigning "American Idol" champion's second single reaches the Triple A top 10 (12-8) and the top half of Adult Top 40 (22-19), helping fuel a Hot 100 debut at No. 100. The song should benefit from his appearance on "Idol" (March 14), its placement in promos for NBC's "Ready for Love," premiering March 26, and his touring with matchbox twenty, ahead of his headlining tour this spring.
Phillips' introductory hit "Home" (No. 37 on the Hot 100 after reaching No, 6), meanwhile, leads Adult Contemporary for an eighth week.

-- Blake Shelton. Miranda Lambert:

Just as they're side-by-side as husband and wife, Blake Shelton logs a third straight week at No. 1 on Hot Country Songs with "Sure Be Cool If You Did," while Miranda Lambert ranks adjacent, vaulting 7-2 with "Mama's Broken Heart." (It's a case of … chart imitating life ...)
Their rankings mark the first instance of the pair placing at Nos. 1 and 2 on the tally concurrently, despite Shelton having scored 13 No. 1s and Lambert, three. Other notable married couples, meanwhile, have never enjoyed such chart closeness. The chart stars, for instance, have never aligned for Tim McGraw and Faith Hill, Garth Brooks and Trisha Yearwood or (since divorced couple) Rodney Crowell and Rosanne Cash to be at Nos. 1 and 2 in the same week. Married couples have sent duets to No. 1, but none of the above partners ranked separately in the top two spots simultaneously until this week.
