Rapid sales movement spells all change at albums chart summit.

Their single Supernatural Superserious peaked at number 54 seven weeks ago but REM still have enough clout to register their eighth number one album to date and their fourth of the 21st century, with Accelerate. First-week sales of 60,778 are lower than their three prior number one albums this decade - Around The Sun opened with sales of 69,676 copies in 2004; the hits compilation In Time with 114,410 sales in 2003; and Reveal with 110,753 in 2001. REM have had more number one albums in the UK than any other American group, but at home their haul is just two - 1991's Out Of Time and 1994's Monster.

It is a good week for urban acts, with debuts from Estelle's Shine (number six, 16,129 sales), Gnarls Barkley's The Odd Couple (number 19, 8,809), Snoop Dogg's Ego Trippin' (number 23, 7,917) and Flo-Rida's Mail On Sunday (number 29, 6,145), all of which are covered more fully elsewhere here.

This week's other new entries come from The Black Keys, Gabriella Cilmi, Michael McDonald, The Specials and Joe Satriani.

Strange Times, the first single from Akron rock duo The Black Keys' new album Attack & Release, fell short of the Top 200 last week, although released simultaneously on seven-inch and download. Nevertheless, the album debuts at number 34 on sales of 5,750, beating both the number 62 peak of their previous highest charting set, 2004's Rubber Factory and the number 79 peak of their last release, Magic Potion (2006).
