Adele‘s multiple Grammy-winning, world record-setting, multimillion copy-selling behemoth of a sophomore album 21 continues to shake up the music world. Just last week, more than a year after its release, the album sold another 75,000 copies, putting it in a three-way tie with Prince’s Purple Rain soundtrack and the soundtrack to Saturday Night Fever with 24 nonconsecutive weeks atop the Billboard 200.

Amazingly, 21 has not left the Billboard Top 10 a single time in the 68 weeks since its release, and has spent 60 of those weeks in the top three. The album has never dropped lower than #7. If 21 can hit 31 weeks at the Billboard apex, it would tie Fleetwood Mac‘s Rumors, the “South Pacific” soundtrack and Harry Belafonte‘s Calypso.

The album is also only a stone’s throw from the coveted diamond sales certification. 21‘s 9.3 million albums sold in the U.S. puts it under a million units away from the elite 10 million-sold status.

At the rate it’s been flying off the shelves, reaching that milestone should be a piece of cake.
