The Beatles' Sgt Pepper's Lonely Hearts Club Band has been named the UK's most popular album of all-time.
The 1967 masterpiece tops the new list, compiled by the Official Charts Company to celebrate National Album Day.
Coming in second was Adele's 21, ahead of Oasis' (What's the Story) Morning Glory?, Pink Floyd's The Dark Side of the Moon and Michael Jackson's Thriller.
The list is based on a combination of sales, streams and downloads.
The Beatles celebrated the 50th anniversary of Sgt Pepper's last year with a new mix of the record, designed to sound better on modern stereo equipment.
Rounding out the top 10 on the Official Charts Company's list were Dire Straits' Brothers in Arms, Michael Jackson's Bad, Fleetwood Mac's Rumours, Amy Winehouse's Back to Black and Adele's 25.
Coldplay had the most records in the top 40 - A Rush Of Blood To The Head at 27, X&Y at 32 and Parachutes at 40.
The highest-ranking album that never reached number one in the charts is The Dark Side of the Moon - it was kept off the top spot by records from Alice Cooper and Led Zeppelin.
Other artists in the top 40 all-time list include Meat Loaf, Lady Gaga, Alanis Morisette, U2, the Spice Girls, Phil Collins, Jeff Wayne and the Corrs.
Oddly, Sgt Pepper's was the only Beatles record in the top 40, despite critics often relegating it to third or fourth behind Abbey Road, Revolver and Rubber Soul.
