Estelle and Duffy continued their reigns as the U.K.'s best-selling single and album artists respectively on new charts Sunday (March 30). Newcomer Sam Sparro had the week's hottest singles climber, while Panic At The Disco scored the highest album debut.

Estelle's "American Boy" (Homeschool/Atlantic) featuring Kanye West started a second week at No. 1, holding off the 6-2 climb of "Low" (Atlantic) by Flo Rida featuring T-Pain.

Sparro, a new priority artist at Universal Island, climbed 23-4 on download sales of "Black and Gold." Also climbing in the top 10 were "4 Minutes" (Warner Bros.) by Madonna featuring Justin Timberlake, 7-5; Chris Brown's "With You" (Zomba), 17-8; and Alphabeat's "Fascination" (Charisma/EMI), back up 13-10.

The former U.S. No. 1 "Love in This Club" (RCA) by Usher featuring Young Jeezy made its U.K. debut at No. 19, while James Blunt's "Carry You Home" (Custard/Atlantic) climbed 65-20.

Duffy's "Rockferry" (A&M/Universal) entered its fourth week as Britain's No. 1 album, pursued by Panic At The Disco's "Pretty, Odd." (Decaydance/Fueled by Ramen). That came in at No. 2 following the band's No. 13 success two weeks ago with the single "Nine in the Afternoon."

"Andidotes," the debut Transgressive album by Oxford, England, quintet Foals, opened at No. 3. A U.S. release is due next week on Sub Pop. The Raconteurs came in at No. 8 with their hurriedly announced sophomore release "Consolers of the Lonely" (XL Recordings), and English outfit Guilletmots were new at No. 9 with their second album "Red" (Polydor/Universal).

Amy Winehouse's "Back to Black" (Universal Island) is in its 12th aggregate week at No. 1 on European Top 100 Albums, while Leona Lewis' "Bleeding Love" (Syco Music/Sony BMG) celebrated its climb to the Billboard Hot 100 summit by regaining the top spot on Eurochart Hot 100 Singles.
