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

-- Taylor Swift, Jason Aldean and Sugarland: The three acts populate Nos. 1-3 on the Billboard 200, marking the first time country albums have monopolized the top three since Nov. 10, 2007. Aldean's arrival at No. 2 with "My Kinda Party" marks not just his highest charting album, but also his best sales week yet (193,000, according to Nielsen SoundScan).

-- "Now That's What I Call Christmas 4": The fourth proper volume in the popular "Now" collection of holiday favorites takes a 65 position jump to No. 70 with 7,000 (up 90%). The 36-track set includes a mix of familiar favorites (Nat King Cole, Bing Crosby) and recently established acts (Lady Gaga, Rihanna). In addition, six holiday sets re-enter the chart this week, a number sure to grow in the march towards Christmas.

-- Chris Tomlin: The Christian singer's 2009 Christmas set "Glory in the Highest" rebounds onto the list at No. 27 with a 670% increase in sales, as it is featured as Family Christian Stores' album of the month. Sale priced at $7.99, it also climbs two spots to No. 4 on the Holiday Albums chart.

-- Paul McCartney & Wings: The band's classic "Band on the Run" album -- No. 1 for four weeks in 1973-1974 -- was reissued last week in an array of different packages and thus climbs back onto the list at No. 29 with a little over 17,000 sold. The week previous, it moved less than 1,000 copies.

-- Michael Jackson: Though his new single "Breaking News" is making waves, his classic 1982 "Thriller" album takes a nose dive on the list this week, descending from No. 92 to No. 190 with a 48% drop in sales. Last week the album charged up the list (up 82%) during the sales week that ended with the Halloween holiday, likely owed to purchasers seeking out his spooky title track.

The Billboard Hot 100

-- Rihanna: The diva rockets to the top of the Billboard Hot 100 as "What's My Name?" (featuring Drake) vaults 60-1 as the chart's Greatest Gainer/Airplay award winner. The track debuts at No. 1 on Hot Digital Songs (235,000, according to Nielsen SoundScan) and charges 24-16 on Hot 100 Airplay with the chart's greatest airplay gain (48.6 million in audience, up 30%, according to Nielsen BDS). "What's My Name?" marks Rihanna's eighth career Hot 100 No. 1 and third this year, following reigns with "Rude Boy" and as a featured artist on Eminem's "Love the Way You Lie." Rihanna is the first artist to score a trio of Hot 100 leaders in a year since she achieved the feat in 2008. "What's My Name?" is Drake's first Hot 100 No. 1 among 23 chart visits.

-- Katy Perry: The singer collects her third top 10 from her "Teenage Dream" album as "Firework" vaults 29-10 with Greatest Gainer/Digital honors. It follows the No. 1's "California Gurls" and the title cut. "Firework" bursts 33-6 on Hot Digital Songs (145,000, up 218%) and blasts 39-27 on Hot 100 Airplay (37.8 million in audience, up 30%).

-- Tim McGraw: Though his "Felt Good On My Lips" has been climbing Hot Country Songs (lifting 14-13 in its seventh chart week), it roars onto the Hot 100 as the Hot Shot Debut at No. 26 following its arrival in the digital marketplace. The song, a new cut from McGraw's double-disc "Number One Hits" collection, due Nov. 30, enters Country Digital Songs at No. 1 and Hot Digital Songs at No. 19 with 64,000 downloads sold.

-- Taylor Swift: "Speak Now," the title cut from the No. 1 Billboard 200 album for a second week, plunges 17-78 on the Hot 100, following the arc of the set's prior digital pre-release tracks. It drops 8-45 on Hot Digital Songs (32,000, down 71%). "Back to December," the set's second country radio single following "Mine," is now being promoted to radio stations as an official single. Swift's "Mine" re-enters Digital Songs at No. 29, after it dropped off the chart entirely last week. Its fall in sales last week was owed to "complete my album" transaction via the iTunes Store. (When consumers opt to upgrade to a full album purchase from a track, those track purchases are counted as returns.)

-- New Hollow: Physical singles, strategically marketed, can still impact the Hot 100. "Sick," the debut single from the youthful pop/rock trio, whose members range in age from 14 to 16, arrives at No. 86 after the song's CD single sold 28,000 copies at Justice retail locations and the girls clothiers' website.
