The Billboard 200:
On the Billboard 200 this past week, Zac Brown Band  scored its second No. 1 album, as "Uncaged" debuted atop the tally with 234,000 sold according to Nielsen SoundScan. It marked the best sales week yet for the country group and the second-largest frame this year for any country album. At No. 2 on the list, Frank Ocean's much buzzed-about album "Channel Orange" arrived with 131,000 -- nearly all from downloads via the iTunes Store.
Aside from our top two this week, there were of course other movers and shakers as well. Let's take a look:
-- One Direction: Last week, One Direction's "Up All Night" become the year's second-biggest selling album in the U.S. according to Nielsen SoundScan, s urpassing Lionel Richie's "Tuskegee."  This week, it further distances itself: 971,000 vs. 943,000. (Adele's "21" is still tops, with 3.7 million.)
On the Billboard 200 chart, "Up All Night" has only left the weekly top 10 once in its 18 weeks. This week, it climbs 11-7 with 36,000 sold.
The set's lead single "What Makes You Beautiful" reached No. 4 on the Billboard Hot 100 singles chart and is 2012's seventh-largest selling digital song (3 million sold). The album's new single, "One Thing," slips 39-41 on the Billboard Hot 100 this week -- but maintains its bullet (indicating continued growth in popularity).
-- Dirty Projectors: The band celebrates its best sales week and highest charting album as the rock act's latest, "Swing Lo Magellan," bows with 14,000 at No. 22. The group's last release (and best seller), 2009's "Bitte Orca," has shifted 87,000 in total.
-- Serj Tankian: The rock singer's new "Harakiri" debuts with 12,000 (No. 29) -- about the same figure that greeted his last release, 2010's "Imperfect Harmonies" (No. 35 with 10,000). The new album's current single, "Figure It Out," is bulleted at No. 16 on the Active Rock airplay chart (where it's been for three straight weeks).
-- Twin Shadow: After spending three weeks on the Uncharted tally, the artist (aka George Lewis Jr.) breaks through to the Billboard 200 for the first time (7,000) with his second album, "Confess." His 2010 debut, "Forget," spent four weeks on Heatseekers Albums -- our tally for new and developing acts.
-- Queen: The band's 1992 "Greatest Hits" collection, thanks to regular discounting at digital retailers, has nearly sold more this year (79,000) than in all of 2011 (92,000). This week the set rises from No. 162 to No. 59, selling 7,000 copies.
