"The Essential Michael Jackson" (Epic/Sony Music Entertainment) is the U.K.'s No. 1 artist album for a fourth straight week, but it was outsold by the new entry at the top of the compilation album chart, "Now That's What I Call Music 73" (Virgin/EMI/UMTV). Sunday's new sales data also showed a second week atop the singles chart for Epic/Sony newcomers JLS with "Beat Again."

The Jackson compilation stayed ahead of Florence and the Machine's "Lungs" (Universal Island), which spends a third week at No. 2. Lady GaGa's "The Fame" (Interscope/Universal) climbed again 5-3 in its 28th chart week, its highest ranking for two months. Paolo Nutini's "Sunny Side Up" (Atlantic/Warner Music) and La Roux's self-titled Polydor/Universal debut were also back up again, 6-4 and 8-5 respectively.

Three more albums rejoined the top ten: Black Eyed Peas' "The E.N.D. (The Energy Never Dies)" (Interscope/Universal), up 13-8; Noisettes' "Wild Young Hearts" (Vertigo/Universal), 16-9; and Kasabian's "West Ryder Pauper Lunatic Asylum" (Columbia/Sony Music Entertainment), 11-10. Jordin Sparks got a No. 11 debut with "Battlefield" (Jive/Sony Music Entertainment), as the title track single rose 15-11.

As last week, Jackson has nine albums in the top 40. Although the 25th anniversary edition of "Thriller" dropped 34-50, a new "Collection" released by Epic last week debuted at No. 14. Further down the chart, blind Aborigine singer Geoffrey Gurrumul Yunupingu re-entered the top 75 at a new peak of No. 48 with "Gurrumul" (Dramatico). The artist won two ARIA Awards in Australia last year.

The JLS single is No. 1 again ahead of a new entry at No. 2 for "Supernova" (Mercury/Universal) by London & Birmingham band Mr. Hudson featuring Kanye West. Pitbull's "I Know You Want Me (Calle Ocho)" (Positiva/Virgin/EMI) climbed again 9-7 and Beyoncé's "Sweet Dreams" (Columbia/Sony Music Entertainment) improved 13-9.

The Pitbull single climbs 2-1 on Eurochart Hot 100 Singles, while Jackson continues to hold down the top four titles on European Top 100 Albums, with "King of Pop" in a third week at the summit.
