First she crushed ’N Sync and then she broke the ratings system itself: Adele’s 25 sold 3.38 million copies in its first week, Billboard reports, the single largest sales week for an album since Nielsen first started monitoring point-of-sale music purchases in 1991. 25 is the first album to sell more than 3 million copies in a week in Nielsen history. Your faves might want to start blaming things on the River Lea (or perhaps Adele’s decision to keep her album off streaming services), because this means that Adele has already won the title for biggest selling album of 2015 — passing Taylor Swift’s 1989, which could only shake shake shake off 1.8 million in sales. By some estimates, 25’s album sales may surpass 4 million by the end of the year.
