The Grammys: Adele, Kanye West Top Nominees
The Grammys: Adele, Kanye West Top Nominees

It's a sleepy post-Easter week on the Billboard 200, as there isn't a single debut in the top 10 -- the first time that has happened since the tally dated Jan. 22. And not a single album in the top 40 posts a sales gain. Things should brighten up next week, once a bevy of new sets from the likes of Beastie Boys and Jennifer Lopez reach the tally.

Meanwhile, at No. 1 this week -- again -- is Adele's "21," marking its sixth nonconsecutive week atop the tally (124,000; down 19%, according to Nielsen SoundScan). It's just the fifth album by a woman in the last 10 years to earn as many weeks at No. 1. Since 2001, the only other female solo albums with six weeks in the penthouse are Norah Jones' "Feels Like Home," Susan Boyle's "I Dreamed a Dream" and Taylor Swift's "Speak Now" and "Fearless." (Swift's latter album has logged 11 weeks total at No. 1).

The chart's highest new entry is from Explosions in the Sky with their sixth album, "Take Care, Take Care, Take Care," starting at No. 16 with 19,000. That immediately trumps the act's previous high, which came with its previous effort, 2007's "All of a Sudden I Miss Everyone," which spent three weeks on the list, peaking at No. 86.

Back in the top 10, Foo Fighters' "Wasting Light" steps 3-2 with just 34,000 (down 52%) while Mumford & Sons' "Sigh No More" climbs 7-3 with 32,000 (down 17%). Britney Spears' "Femme Fatale" rises one rung to No. 4 (30,000; down 34%), the "Lemonade Mouth" soundtrack falls one spot to No. 5 (nearly 30,000; down 57%), and Chris Brown's "F.A.M.E." ascends three places to No. 6 (28,000; down 22%). Katy Perry's "Teenage Dream" jumps three to No. 8 (24,000; down 31%), Wiz Khalifa's "Rolling Papers" slides 12-9 (nearly 24,000; down 30%), and Paul Simon's "So Beautiful or So What" falls 8-10 (almost 24,000; down 36%).

Last week's No. 2 album, "Glee, the Music Presents: The Warblers," slides five rungs to No. 7 in its second week (28,000; down 68%). Despite its tumble, lead Warbler Darren Criss has reason to celebrate. He wrote the music and lyrics to the musical "Starship," whose cast recording bows at No. 134 on the Billboard 200 and at No. 1 on our Top Cast Albums chart (4,000 sold). The set was released exclusively through digital retailers on Friday, April 29, meaning it bows on the list this week with just three days of sales. (The tracking week ends on Sunday, May 8.)

Over on the Digital Songs chart, Perry's "E.T." continues to hold court at No. 1 with a little more than 300,000 (down 13%), barely edging out Adele's "Rolling in the Deep," which is steady at No. 2 (with almost 300,000; up 1%). Making an expected leap up the tally is Spears' "Till the World Ends," which rallies 12-3 with 246,000 (up 102%). Its gain is fueled by the much-hyped new remix of the song featuring Nicki Minaj and Ke$ha.

Bruno Mars' "The Lazy Song" holds at No. 4 (194,000; up 3%), the Black Eyed Peas' "Just Can't Get Enough" falls two to No. 5 (176,000; down 15%), and Tinie Tempah's "Written in the Stars" (featuring Eric Turner) rises 11-6 (144,000; up 12%). Ke$ha's "Blow" climbs two spots to No. 7 (143,000; down 5%), Jennifer Lopez's "On the Floor" is down one to No. 8 (139,000; down 14%), and Brown's "Look at Me Now" also falls a rung to No. 9 (131,000; down 14%). Closing out the top 10 is Cee Lo Green's "F**k You (Forget You)," rising 13-10 (124,000; up 3%). The Digital Songs chart's highest debut is the Glee cast's mash-up of "I Feel Pretty" (from "West Side Story") and TLC's "Unpretty," which bows at No. 13 with 112,000.

Noticeably absent from the top 10 on Digital Songs are two closely-watched singles from two divas with highly-anticipated albums on the way. First is Lady Gaga's "Judas," which descends 6-19 in its third week on the chart with 81,000 (down 48%). "Judas" is the second offering from Gaga's third studio release, "Born This Way," due out May 23. Secondly, Beyonce's "Run the World (Girls)" slips 23-39 with 47,000 (down 39%) in its second week on the tally. It's the lead single from B's fourth as-yet-untitled solo album, expected later this year.

Overall album sales in this past chart week (ending May 1) totaled 5.4 million units, down 17% compared with the sum last week (6.5 million) and down 2% compared with the comparable sales week of 2010 (5.5 million). Year-to-date album sales stand at 101.9 million, down 2% compared with the same total at this point last year (103.7 million).

Digital track sales this past week totaled 25.3 million downloads, down 5% compared with last week (26.7 million) and up 18% stacked next to the comparable week of 2010 (21.5 million). Year-to-date track sales are at 438.4 million, up 10% compared with the same total at this point last year (400 million).

Next week's Billboard 200 competes with the same week in 2010 when: Godmack's "Oracle" debuted at No. 1 with 117,000 while MercyMe's "The Generous Mr. Lovewell" launched at No. 3 with 88,000. The previous week's topper, B.o.B's "The Adventures of Bobby Ray," fell to No. 12 in its second week with 36,000 (down 57%).
