For Mariah Carey, E=MC Ka-Ching!

Mariah Carey looks certain to debut at No. 1 on next week's U.S. pop album chart, based on massive first-day sales. The first single from the new album, "Touch My Body," has spent two weeks at No. 1 on Billboard's Hot 100 chart.

The new and improved diva's follow-up to her 2005 smash "The Emancipation of Mimi," sold 154,000 units Tuesday. That's more than five times the first-day haul for the current Billboard 200 champ, Leona Lewis' "Spirit," which ended up selling almost 205,000 copies in the week ended April 13.
