Swift’s sixth studio album, released Friday, is her fourth to sell 1 million records in a week. Past records achieving the feat include “1989,” “Red” and “Speak Now.” She’s the only artists ever to have four million-selling weeks since Nielsen Music started tracking music sales electronically in 1991, according to Billboard.
"Reputation" is the first album in two years to sell a million copies in a tracking week. The last record to do so was Adele's "25" in 2015. That album sold 3.48 million its first week.
