Danity Kane's Welcome to the Dollhouse goes straight to the penthouse on The Billboard 200, the second No. 1 in a row for the group. The MTV Making the Band 3 troupe, signed to Diddy's Bad Boy imprint, moved 236,000 copies of its sophomore effort in the United States, according to Nielsen SoundScan. Danity Kane's 2006 self-titled debut also started at the top, with 234,000.

It's only March, but Dollhouse enjoys the second-biggest sales week of the year. Only Jack Johnson's Sleep Through the Static had a bigger bow when it debuted at No. 1 with 375,000 in February. Static falls 4-5 in its seventh week on the chart with 67,000, despite a 21% increase.

The multi-label NOW 27 compilation experiences a 1 percent uptick in sales to 170,000 copies, holding tight at No. 2. Last week's No. 1, Rick Ross' Trilla (Slip-N-Slide/Def Jam), slips to No. 3 with a 54 percent sales decrease to 90,000.

Fueled by his chart-topping single "Low," Flo Rida's debut album Mail on Sunday (Poe Boy/Atlantic) bows at No. 4 with 86,000. The rapper has the biggest-selling digital download of all time, as "Low" has sold 3.3 million downloads since its November release.

Miley Cyrus' Disney double-disc Hannah Montana 2 (Soundtrack)/Meet Miley Cyrus rockets 16-6 with a 137 percent sales boost to 61,000. Additionally, her The Best of Both Worlds Concert set clings to No. 10 with 51,000 (+48 percent). But Cyrus' albums aren't the only kid-friendly releases to score bigger numbers this week in the wake of the Easter holiday.

Taylor Swift's self-titled Big Machine album enjoys a 74 percent increase to 57,000 (12-8), Sara Bareilles' Little Voice (Epic) has a 38 percent sales gain to 55,000 (7-9), the Fox/Razor & Tie soundtrack to Alvin and the Chipmunks jumps 49 percent to 48,000 (15-11), and the Jonas Brothers' self-titled Hollywood set rockets 197 percent to 47,000 (17-12).

The Disney soundtrack to Enchanted also bolts 149-39 with a 281 percent gain to 18,000, after the film hit DVD last week. Snoop Dogg's Ego Trippin' (Geffen) fills out the top 10, falling 3-7 with 57,000 (-58 percent).

Further down, Gnarls Barkley's sophomore album, The Odd Couple (Downtown/Atlantic) begins at No. 18 with 31,000. The set was rushed to market last Tuesday (March 18), weeks ahead of its original April 8 release date, likely because of an early leak online. Eighty-five percent of the sales were via online retail. Rapper Rocko's Self-Made (Rocky Road Records/Universal) is also new at No. 21 with 28,000.

Album sales this week are up 11.3 percent over the prior week to 8.83 million and down 1.1 percent compared to the same week in 2007.
