Ross goes 2-for-2 at No. 1

Rapper leads five debuts in top 10

Rick Ross muscles out a compilation cash cow and a hip-hop veteran as rookie albums take the top three spots on the Billboard 200 this week.

The Miami rapper's "Trilla" (Slip-N-Slide/Def Jam) bows with 198,000 units sold, giving Ross his second No. 1 debut in as many tries. His first album, "Port of Miami," sold 187,000 in its opening week in 2006.

The 27th album in the "Now That's What I Call Music" series, released by opens at No. 2 with 169,000 copies. Sounds like a pretty hefty number for today's music climate, right? Consider this: The Universal/Zomba/Sony BMG release sees the lowest opening sales week for a regular "Now" album since the first in the series bowed with 48,000 in 1998. All but four of the compilations have opened with at least 200,000 units sold.

Snoop Dogg represents the West Coast with "Ego Trippin' " (Doggystyle/Geffen), his highest-charting album since 1999. But that fact is misleading because the new record's 137,000 copies is the fewest for any of the rapper's nine studio albums.

Fat Joe matches his career chart peak with "The Elephant in the Room" (Terror Squad/Imperial). The Bronx rapper's "All or Nothing" reached No. 6 in 2005.

Destiny Hope Cyrus by any name is a top 10 threat. The singer-actress, who had her name legally changed to Miley Ray Cyrus this week, returns to the top tier with "Hannah Montana & Miley Cyrus: Best of Both Worlds Concert" (Hollywood/Walt Disney), which bows at No. 10.

A little 2008 perspective: This week's 10th-best-selling disc moved 34,000 units. The No. 10 album for the same week of 2007, Carrie Underwood's "Some Hearts," sold 42,000. The average total of the No. 10 album for the same week of the year during the past 10 years? 63,623.

Elsewhere in the top 10: Jack Johnson's "Sleep With the Static" dips two spots to No. 4 (Brushfire, 55,000 units), and last week's top seller, "Good Time" by Alan Jackson, falls to No. 5 (Arista Nashville, 53,000).

Sara Bareilles holds at No. 7 with "Little Voice" (Epic, 40,000), Janet Jackson's "Discipline" slides five notches to No. 8 (Island, 38,000), and Erykah Badu's "New Amerykah: Part One (4th World War)" slips three to No. 9 (Universal Motown, 35,000).

Overall album sales this week are up 3.4% over last week to 7.94 million but down 6.6% from the same week in 2007.
