Queen have made UK chart history by becoming the first act to sell seven million copies of an individual album.
Their first Greatest Hits collection, from 1981, is now owned by one in every four households in the UK, said the Official Charts Company.
The record, which features classic singles like We Will Rock You and Bohemian Rhapsody, has been a perennial best-seller for years.
It recently spent its 1,000th week on the UK album chart, reports BBC.
Queen guitarist Brian May called the latest achievement "joyous news".
"No album has done this before in history," he said in a statement. "Thank you, we appreciate it."
Drummer Roger Taylor added: "The British public and their infinitely-great taste have made this the biggest-selling album in history.
"Thank you very much; we're humbled and honoured. We salute you!"
Queen's Greatest Hits leads the all-time album chart by almost a million copies, ahead of Abba's 1992 compilation album Gold.
"When it was released for the first time in 1981, career-spanning packages such as Greatest Hits were relatively rare, the preserve of only the very biggest acts," noted Martin Talbot, chief executive of the Official Charts.
"There is no doubt that its massive success has done as much as any other release to turn hits packages into the omnipresent album concept that they are today."
Queen's second Greatest Hits album, released in October 1991, a month before the death of singer Freddie Mercury - is also the UK's tenth biggest record, with sales around the four million mark.
Back in 2014, Queen's Greatest Hits became the first album to surpass six million sales in the UK.
At the time, the chart only counted "pure" sales - ie vinyl, cassette, CD and downloads.
A year later, audio streams were incorporated into the calculations, with 1,000 streams counting as one "sale".
Since then, Queen's Greatest Hits has accumulated 1.26 billion total UK streams, which are counted as 1.26 million sales.
The album's most-streamed track being Bohemian Rhapsody, which boasts 240 million UK streams and counting, the chart company said.
The band's back catalogue received a massive boost from the release of the Oscar-winning Freddie Mercury biopic Bohemian Rhapsody in 2018.
On Spotify, Queen are currently the 31st most-streamed act in the world, ahead of other classic artists like The Beatles, who place 44th, and Michael Jackson, who is 68th.
