Taylor Swift is ending the year in one of the best ways possible -- with the top-selling album of the year.

Swift's pop album '1989,' which has only been on sale for nine weeks, surpassed sales of Disney's 'Frozen' soundtrack during the final week of the year.

According to Nielsen Music, Swift's album sold 3.66 million copies next to the 3.53 that 'Frozen' sold during the tracking year, which ran from Dec. 30, 2013, to Dec. 28, 2014. 'Frozen' maintained the No. 1 spot in every tracking week of the year until '1989' overtook it last week, when Swift's album sold 326,000 copies to the soundtrack's 64,000.

Swift previously took home the top selling album of the year in 2009 with her second studio album 'Fearless,' selling 3.22 million copies that year.

This is only the second instance where the top selling album has changed in the last week of tracking. In 1994, Disney's 'The Lion King' soundtrack overtook 'The Sign' by Ace of Base to claim the No. 1 spot.

This year, Sam Smith takes the No. 3 spot with 1.21 sales of 'In the Lonely Hour' and Pentatonix comes in at No. 4 with 'That's Christmas To Me' (1.14 million sales).
