Mariah Carey tops Billboard for second week

Leona Lewis' 'Spirit' in second spot

Appearances on TV's most popular show helped Mariah Carey and Leona Lewis rule the Billboard 200 again, but the top 10 has four new residents this week, two of which are making their first visit.

The debut album by New Zealand's fourth-most-popular digi-folk paradists Flight of the Conchords leads the rookie parade. The duo's set doubles as a soundtrack to their HBO series. Right behind them is Ashlee Simpson's third album, "Bittersweet World." The Texas popster's first two sets debuted at No. 1, selling 398,000 and 220,000 units, respectively.

Indie hip-hop act Atmosphere easily scores a chart and sales best with "When Life Gives You Lemons, You Paint That Shit Gold." The veteran Minneapolis duo also gives its label Rhymesayers a new chart peak; its previous best was No. 66 with Atmosphere's 2005 set.

"Prayer for a Common Man" gives country singer-songwriter Phil Vassar his first top 10 with a studio effort. The Virginia native's hits disc also bowed at No. 10 in 2006, but his previous high for a new album was No. 44 for 2002's "American Child."

Overall albums sales were 6.87 million units, down 8% from the previous week and 11% for the same frame last year.

Billboard analyst Keith Caulfield contributed to this report.
