Adele’s 21 Debuts At #1 On Billboard 200

British singer knocks Justin Bieber from top spot, but Biebs still has two albums in top five.

We called it! As predicted on MTV News last week, Grammy-winning British soul sister Adele will nab the #1 spot on the Billboard 200 chart next week with her new album, 21, which sold 352,000 copies to easily take the crown.

According to figures provided by Nielsen SoundScan, that was more than enough to outpace last week’s #1, Justin Bieber’s Never Say Never – The Remixes, which drops a spot to #2 as sales trailed off by 38 percent to 102,000. The 17-year-old pop sensation has nothing to worry about, though, as the remix effort was just one of two albums he has in the top five, the other being his nearly year-old My World 2.0, which lands at #5 on sales of 42,000.

In an otherwise slow week with few new releases, most of the rest of the top 20 saw double-digit declines, as the Grammy effect started to wear off on a number of artists. The rest of the top 10: Mumford & Sons, Sigh No More (#3, 71,000, down 46 percent), NOW 37 (#4, 58,000, down 37 percent), Bruno Mars, Doo-Wops & Hooligans (#6, 37,000, down 40 percent), Eminem, Recovery (#7, 34,000, down 44 percent), Rihanna, Loud (#8, 33,000, down 26 percent), Nicki Minaj, Pink Friday (#9, 32,000, down 30 percent) and Lady Antebellum, Need You Now (#10, down 67 percent).

Though she couldn’t pull off the Bieber top five double-play, Adele’s 2008 debut, 19, continues its march back up the charts, jumping 34 spots to #16 on sales of 18,000. Meanwhile, the short-lived Grammy bump for Arcade Fire seems to be over, as the disc slips five spots to #17 as sales plummeted by 59 percent to 17,000. And after coming in at #13 last week, Bright EyesThe People’s Key dives 28 slots to #41 as sales trailed off by 72 percent to 11,000.

Former Fall Out Boy singer Patrick Stump has a modest debut at #67 with his first EP, Truant Wave (7,000).

Things were much the same on the iTunes charts, where Adele tops the album tally, followed by Mumford, Bieber’s My World 2.0 and his remix album, then Adele’s 19, Rihanna, Lupe Fiasco‘s Lasers, Stump, Florence and the Machine‘s Lungs and Eminem.

Lady Gaga continues to lord over the iTunes singles chart with “Born This Way,” edging out Cee Lo Green‘s “Forget You.” Jennifer Lopez‘s “On the Floor” comes in at #3, followed by Rihanna’s “S&M,” Katy Perry‘s “E.T.” and Adele’s “Rolling in the Deep.” Rounding out the list are Dr. Dre and Eminem with “I Need a Doctor” (#7), Pink‘s “F—in’ Perfect,” Ke$ha‘s “Blow”
and Bruno Mars’ “Grenade.”

Things should be pretty static at the top next week, with the only new releases coming from former Floetry member Marsha Ambrosius , as well as new albums from Lucinda Williams and Harry Connick Jr. and the debut from former Oasis singer Liam Gallagher’s new band, Beady Eye.

I'm so fancy.
