"X Factor" winner Leona Lewis retained her singles crown on yesterday's (Jan. 14) new U.K. sales charts, as "A Moment Like This" (Syco Music/Sony BMG) narrowly held off "Proper Education" (Data/Positiva) by Eric Prydz vs. Floyd. Meanwhile, Amy Winehouse reached the top of the album chart for the first time as "Back to Black" (Universal Island) rose 2-1.

As Lewis started a fourth week at No. 1, the singles chart had strong debuts for two newcomers. Mika, the recording name of Lebanese-born Mica Penniman, justified his place at the top of many critics' prediction lists for 2007 success as "Grace Kelly" (Casablanca/Universal Island) started at No. 3, while singer-rapper Just Jack came in at No. 4 with "Starz in Their Eyes" (Mercury).

American star JoJo scored a third U.K. top 10 hit as "Too Little Too Late" (Mercury) rose 22-6. The move underlined that despite last week's chart eligibilty changes to allow digital-only releases into the survey, a physical release one week after the digital version can still give a track a significant boost. The same is true of "Rain Down Love" (Loaded) by Freemasons featuring Siedah Garrett, which races 51-12 after physical release.

New on digital sales were The View's "Same Jeans" (Columbia) at No.11 and Klaxons with "Golden Skans" (Polydor) at No. 15. Winehouse's stellar week was boosted further by a climb of 40-18 for the single "You Know I'm No Good." The chart also contained a 49-22 climb for the Ordinary Boys' "I Luv U" (Polydor) and a No. 31 entry for Koopa's "Blag, Steal Or Borrow."

That trio from Essex have been widely reported in recent media coverage as the first unsigned act ever to score a top 40 entry, a somewhat misleading description as there is nothing new in the concept of self-released material. But Koopa are indeed the first act to use the new digital-friendly chart rules to score a top 40 single without incurring any physical manufacturing, marketing or distribution costs.

Winehouse's album reached No. 1 in its 11th chart week, as Take That's six-week run with "Beautiful World" (Polydor) ended with a fall to No. 4. Their Polydor labelmate James Morrison's "Undiscovered," already double platinum for 600,000 shipments, climbed 5-2 in its 24th week. The one significant new entry, at No. 7, was Kylie Minogue's "Showgirl -- Homecoming Live" (Parlophone), the release of which coincided with the Australian entertainer's first British concerts since her cancer treatment.

The Beatles' "Love" (Apple) leads the way on European Top 100 Albums for a seventh straight week. Their biggest challenger, up 5-3 in its 30th week on the chart, is Nelly Furtado's "Loose" (Geffen). Its current single, "All Good Things (Come To An End)," rises 2-1 on Eurochart Hot 100 Singles after reaching No. 1 in Germany, Austria and Switzerland.
