Adele's highly-anticipated album, 25, finally went on sale Friday -- and it's already poised to break records.
According to Billboard, the album is on track to sell at least 2.5 million copies in its first week, which means it would break *NSYNC's current one-week U.S. sales record of 2.42 million. (The band's album No Strings Attached set the record in 2000.)
On the day of its release, 25 sold 900,000 copies on iTunes alone. If industry forecasters are right, it will become the largest-selling album of 2015, surpassing Taylor Swift's 1989 (which came out in 2014.)
