You can talk all you want about how the cratering music business has allowed Adele's 21 to dominate charts for like 70 weeks, but here's a fact about 21 that is true and seems impossible: In the U.K., 21 is now more popular than Thriller, as it has sold 4,274,300 copies compared to 4,273,800 for Thriller. That's a margin of only 500, but still: 21 > Thriller in the U.K.
Adele has a decent chance of having the number one album in the history of the U.K., as she's already at number five on the list, behind Oasis' What's the Story Morning Glory?, ABBA's Gold, Sgt. Pepper's Lonely Hearts Club Band, and Queen's Greatest Hits. [Fact Mag]
