Despite creating a new slang term with his smash single, "Ay Bay Bay," Louisiana native Hurricane Chris disappoints on this week's Billboard 200, not even cracking the top 20.

In fact, no R&B or hip-hop albums were in the top 10 this week, unless you count Kid Rock, whose album Rock N Roll Jesus landed at no. 7. Otherwise, no hip-hop or R&B albums.

But, news on the charts this week, is that Kanye West's Graduation finally falls from the top 10 to no. 16 after seven weeks, moving 43,300 copies.

At no. 18 is Soulja Boy, who scanned 34,700 units this week of his debut album, Souljaboytellem.com, while Keyshia Cole's sophomore effort, Just Like You, claims no. 19 with 32,200 CDs grabbed off shelves.

Just outside the top 20 is Philly songstress Jill Scott's Words and Sounds: Vol. 3, which claims no. 23 with 26,800 discs sold, and Mr. Ay Bay Bay himself, Hurricane Chris, opens at no. 24 with 51/50 Ratchet, selling just 26,200 copies, despite the overwhelming success of his single.

50 Cent's Curtis continues to fall -- from no. 21 to no. 30 this week, moving 23,800 copies, putting his total at 1,049,300.

Other debuts down the line included duo Little Brother, who bows at no. 89 wit Get Back, selling 9,500, with their first album back at ABB Records.

Houston rapper Trae's Life Goes On debuted at No. 104 with 7,500 copies sold.

According to Billboard.com, album sales are up 5.2% from last week at 8.34 million units and down 16.8% from the same week in 2006 (10.03 million).
