Cash 'n' Carey yet again

Diva's 6th No. 1 is top debut of '08

After "Emancipation," a proclamation: Mariah Carey is all the way back.

Obliterating any cloudy memories of her "Glitter" fiasco, the pop diva attacks the Billboard 200 this week with "E=MC2," her sixth No. 1 album. The follow-up to her comeback smash "The Emancipation of Mimi," the biggest-selling album of 2005, gives Carey the best opening week of her career and the largest first-week total of any record this year.

The full-throated singer-songwriter is now tied with Madonna and Janet Jackson for the second-most No. 1 albums, behind only Barbra Streisand's eight. It should be a brief three-way tie, however, as Madonna's "Hard Candy" streets Tuesday.

No tears for Carey, though: Her albums have sold a combined 50 million units in the 17-year SoundScan era, third on the list behind Garth Brooks (67.8 million) and the Beatles (56.2 million).

The only other new entry in the top 10 this week is the self-titled debut from country trio Lady Antebellum. It's the first rookie album by a duo or group to debut at No. 1 on Billboard's Top Country Albums chart.

Meanwhile, a pair of former top 10 mainstays roar back into the upper echelon. "Hannah Montana/Miley Cyrus: The Best of Both Worlds Concert" vaults from No. 31 to a new peak of No. 3 with a 162% gain. The set became available to all music sellers last week after spending its first five weeks of release as a Wal-Mart exclusive. Coincidentally, the "Juno" soundtrack also sees a 162% surge, spurred by the DVD release of the Oscar-nominated comedy. The set rockets 38 notches.
