From Pentatonix to Jessie J, 2015 is churning out some excellent holiday tunes, and Carly Rae Jepsen has just served what may be the best one yet.

The "I Really Like You" star unveiled an awesome new version of Wham!'s "Last Christmas," with synths and saxophone blasts that fall right in line with the production elements that were popular when the song originally dropped in 1984.

Fans who also love CRJ's new Emotion album will also dig this, since it recalls a lot of the tunes on the album—the sax will particularly remind you of "Run Away With Me"—but now with an Xmas twist!
