Adele Notches Ninth Week At #1 On Billboard

Hard rockers Seether debut at #2, and Il Volo crack top 10 following 'American Idol' performance.

[artist id="2476941"]Lady Gaga[/artist] will surely end Adele's reign next week, but for now the British chanteuse continues lording over the Billboard 200 with her smash album 21. According to figures provided by Nielsen SoundScan, the unstoppable "Rolling in the Deep" singer will notch her ninth non-consecutive week at #1 thanks to sales of 138,000, which bring her U.S. totals to nearly 1.9 million so far.

Way behind at #2 are hard rockers Seether, whose Holding Onto Strings Better Left to Fray comes in at #2 with sales of 61,000.

The only other debut in the top 10 is from pop-opera trio Il Volo, whose self-titled album has a modest bow at #10 thanks to 23,000 units moved, a soft total considering they appeared on the penultimate "American Idol" performance show.

The rest of the top 10: Now 38 (#3, 50,000); Jason Aldean, My Kinda Party (#4, 29,000); Mumford & Sons, Sigh No More (#5, 25,000); Beastie Boys, Hot Sauce Committee Part Two (#6, 24,000); the Lonely Island, Turtleneck & Chain (#7, 24,000); Justin Bieber, Never Say Never - The Remixes (#8, 23,000); and Fleet Foxes, Helplessness Blues (#9, 23,000).

Landing just outside the top 10 at #11 is the spaghetti western-influenced collaboration between producer Danger Mouse and Daniele Luppi, Rome (23,000), and the self-titled debut from "America's Got Talent" winner Michael Grimm at #13 (22,000). British rap import Tinie Tempah's Disc-Overy lands at #21 (16,000), while the New Boyz' Too Cool to Care comes in at #41 (12,000).

The jury still appears to be out on "Glee" star Matthew Morrison's self-titled debut, which falls 31 spots from its #24 debut last week to #53 as sales dropped off by 43 percent to 9,000.

Adele also continues her domination on the iTunes charts, topping the album tally, followed by the digital version of Gaga's Born This Way, Seether, Parachute's The Way It Was, Lonely Island, reformed cult college band Dispatch's self-titled effort, Mumford & Sons, Rome, Il Volo and the soundtrack to the Tony-nominated Broadway show "The Book of Mormon."

The iTunes singles chart continues to be topped by Adele's "Rolling in the Deep," which beats out Pitbull's "Give Me Everything," LMFAO's "Party Rock Anthem, Gaga's "Hair," Bruno Mars' "The Lazy Song," Jennifer Lopez's "On the Floor," Katy Perry's "E.T.," the Black Eyed Peas' "Just Can't Get Enough," Nicki Minaj's "Super Bass" and Lupe Fiasco's "The Show Goes On."

Gaga will smash the top next week, when new albums from Brad Paisley, NKOTBSB and Foster the People will also make their chart debuts.
