Chart leaders Keane remained at number one with Strangeland despite sales of 19,982, a sales dip of 58.23% on the previous week.
Music Week reports that the figure represents only the second time a record has sold less than 20,000 copies to achieve number one this century, after Adele's 21 shifted just 17,065 units to win the top spot four weeks ago.
Meanwhile, Tenacious D's Rize of the Fenix debuted at two with sales of 15,971. Their last LP, The Pick of Destiny, shifted 192,127 to enter at number ten in 2006.
Other new entries included Ren Harvieu's Through The Night, which entered at five on sales of 10,943, while Garbage totalled 8,310 to land at number ten.
Outside the top ten, Glee's The Graduation Album reached number 17 selling 5,848, Engelbert Humperdinck's Best Of enters at 21 on 5,420, and Gossip sold only 2,822 copies of their new album A Joyful Noise to finish at 47.
Last year, Coldplay branded album sales as "meaningless" in today's sales climate, adding: "The days of selling tens of millions of copies has gone, so there's no point using that yardstick anymore."
