Dizzee Rascal is at the top of the chart for a third time, as his summery single Holiday made it to number one, seeing off stiff competition.
Last week's number one, Sexy Chick by David Guetta and Akon, slid down to number two.
And it was a good week for the Arctic Monkeys. Their third album, Humbug, shot to the top of the album charts in its first week of release.
Michael Jackson is still doing well as he's got four albums in the top 40.
His 'best of' collection The Essential dropped two places to number eight, while Bad, Thriller and The Very Best of Michael Jackson & Jackson Five clung on at numbers 27, 31 and 34 respectively.
