The Artic Monkeys look set to claim the record for the year's fastest-selling release after fans snapped up 85,000 copies of their new album on its debut in the shops.
Favourite Worst Nightmare outsold the rest of the UK's top 20 albums on Monday, when it went on sale for the first time.
The album is now set to break the sales record achieved by rival band the Kaiser Chiefs, who sold 151,000 copies of Yours Truly, Angry Mob during its first week of release in February.
But music retailer HMV acknowledged that it would be "next to impossible" to match or beat the sales record set by the Artic Monkeys' debut album Whatever People Say I Am, That's What I'm Not.
The initial offering from the Sheffield band sold 363,735 copies in its first week when it was released in 2006, making it the fastest-selling debut album in chart history.
Commenting on the progress of the Artic Monkey's latest title, HMV spokesman Gennaro Castaldo described Favourite Worst Nightmare as "easily the fastest selling album of the year to date".
"If sales continue at this pace, they should certainly top the quarter million mark, which would not only give the band a sure fire number one, but leave them well placed to claim the biggest album of 2007," Castaldo added.
The Arctic Monkeys, who were signed up by Domino Records in 2005, announced earlier this month that they would be playing at this year's Glastonbury Festival.
