Adele’s 25 has been out for two weeks already, but people are still buying up copies. The album broke another record during its second week selling over 1 million copies.

Nielsen Music said on Friday that this is the first time since Nielsen started tracking sales in 1991 that an album has sold at least 1 million copies in two different weeks. It is also only the 20th album since 1991 to sell 1 million copies in a single week.

During its first week, which ended on Nov. 25, 25 sold 3.38 million copies and became the fastest-selling album since 1991. It reached 4 million copies in total by Dec. 1.

Amazingly, three-quarters of all 25’s sales came from physical copies in its second week. During its first week, there was an even split between physical and digital sales, but it looks like Black Friday and Small Business Saturday gave an extra boost to physical copies during week two.

25 made up 37.7 percent of all physical albums sold in the U.S. during its second week. It made up 47.9 percent of all digital album sales.

Final data for 25’s second week will be published by Billboard on Sunday. In the meantime, you can check out our review of the new album by Adele right here.
