Reba McEntire's 'Duets' checks in at No. 1

Reba McEntire's "Reba Duets"--featuring the country singer's collaborations with acts including Kelly Clarkson, Rascal Flatts, Kenny Chesney, Justin Timberlake and Faith Hill--sold about 301,000 copies during its first week in stores, enough to debut at No. 1 on the US album chart.

McEntire beat out last week's No. 1 album, Kanye West's "Graduation," which sold about 226,000 copies during its second week out and slips to No. 2 on The Billboard 200. Rapper 50 Cent's "Curtis" falls from No. 2 to No. 3 on sales of 143,000, according to Billboard, which bases its album chart on Nielsen SoundScan retail reports.

Barry Manilow's "The Greatest Songs of the Seventies" moved 113,000 copies during its first week in stores, and checks in at No. 4. Kenny Chesney's "Just Who I Am: Poets & Pirates" moves down two notches to No. 5, on sales of 112,000 copies.

Rounding out the Top 10 are the "High School Musical 2" soundtrack, James Blunt's "All the Lost Souls," Chamillionaire's "Ultimate Victory," KT Tunstall's "Drastic Fantastic" and Twista's "Adrenaline Rush 2007."
