A look at some of the most notable movers and shakers on this week's Billboard 200 albums and Hot 100 singles charts.
The Billboard 200
-- Lady Antebellum: At No. 12, the trio's "A Merry Little Christmas" EP flies with a 58-position increase (up 175%, according to Nielsen SoundScan) thanks to blowout sale pricing. The Target-exclusive sing-song set also motors 13-4 on Top Country Albums. The charts regularly house weird jumps from clearance-priced Christmas albums every January, so this Lady A gain isn't too shocking.
-- Usher: After his "Versus" EP was Amazon MP3's daily deal on Jan. 7 (for $3.99), it earns an overall gain of 13% and a jump of 523% in downloads (rising 66 slots to No. 88). Of its nearly 6,000 copies sold this week, 43% of its sales were digital.
-- Edward Sharpe & the Magnetic Zeroes: The act's "Up From Below" re-enters at No. 121 (4,000; up 14%) thanks perhaps to a new viral video making the rounds that stars an unlikely duo covering the album's "Home." It features 24-year-old Jorge Narvaez and his 6-year-old daughter Alexa, and has been viewed more than 2 million times since it was posted to YouTube on Dec. 31.
-- Cristian Castro: The singer's tribute album to Jose Jose, "Viva El Principe," vaults 64 positions to No. 122 (4,000; up 2%). The gain -- owed to promotion and positioning at key accounts -- is impressive as Latin album sales are down 18% this week, while overall album volume declined by 24%.
-- Jackie Evancho: The chart's mightiest fall this week belongs to the pint-sized singer's "O Holy Night" EP, which tumbles 112 slots to No. 151 (down 79%). It's not a surprising fall, by any means, since it's a Christmas set and most holiday efforts fall apart come January.
The Billboard Hot 100
-- Bruno Mars: He circles back to the top of the Billboard Hot 100 as "Grenade" once again replaces Katy Perry's "Firework" at No. 1 (1-2). "Grenade" supplanted "Firework" two weeks ago, only to have Perry's track reclaim the chart's lead spot for a fourth cumulative frame on last week's ranking. It is the first time two songs have alternated holds at No. 1 over four weeks since "Live Your Life" by T.I. (featuring Rihanna) traded spots with Beyonce's "Single Ladies (Put a Ring On It)" in December 2008. Mars' track remains entrenched atop Hot Digital Songs for a fourth straight week with 275,000 downloads (down 35%), according to Nielsen SoundScan, as the post-holiday glow has finally worn off the digital download market as total sales dip by 29% this week.
-- Britney Spears: Threatening the reign of Mars' "Grenade" or the return of Perry's "Firework" to No. 1 next week will be the arrival of Britney Spears' "Hold It Against Me" which was released near-simultaneously at radio (Jan. 10) and exclusively at iTunes (Jan. 11). With airplay off to a blazing start and track sales set to exceed 400,000, according to industry sources, a second No. 1 debut for the pop starlet is likely. She previously started at the summit with "3" on the chart dated Oct. 24, 2009.
-- Chris Brown: The singer continues his road to redemption as he enters the top five on Hot R&B/Hip-Hop Songs with "No BS," while his pop-centric effort "Yeah 3X" continues its Hot 100 climb (91-75) while soaring 16-10 on Hot 100 Airplay, his 12th top 10 on that chart. Since he first charted in 2005, only T-Pain (16) and Rihanna (15) have had more top 10s. "Yeah 3X" also rises 13-12 on the Mainstream Top 40 radio list, his best showing on that chart since "Forever" peaked at No. 1 for five weeks in the summer of 2008, months before his pre-Grammy incident with Rihanna occurred.
-- Gwyneth Paltrow: She charts a third title on the Hot 100 with "Country Strong," the title track from the motion picture in which she stars, which is the top debut at No. 81. The song shifts 32,000 (up 130%). She previously placed two tracks on the Hot 100 in December from her guest starring turn on "Glee." Paltrow is now not too far behind hubby Chris Martin, who's appeared 10 times on the Hot 100 (nine with Coldplay) since 2001.
-- Flo Rida: The rapper's "Who Dat Girl," featuring Akon, is the top Digital Gainer, rising 53-39. The track is the only title that was on the 75-position Hot Digital Songs chart a week ago to post a sales increase this frame (up 6% to 63,000). The only other actual increases on Hot Digital Songs come from debuts and re-entries. "Who Dat Girl" is rising on the Mainstream Top 40 chart (28-25, up 20% in plays).
