Christmas Pop Playlist: Mariah Carey, Pentatonix, *NSYNC + More

It's that time of year again! Sure, for those who celebrate Christmas it's time to trim the tree and wrap thoughtful gifts for your loved ones. But let's not forget another just-as-valid annual holiday moment: When you hear those opening bars of Mariah Carey's "All I Want For Christmas Is You" for the very first time in the season, adding a festive touch to your perusal of the CVS aisle's cotton swab selection.

Many of our much-loved pop stars have contributed enduring original holiday singles over the decades, from Wham!'s "Last Christmas" (recently covered by Carly Rae Jepsen) to instant-favorite "That's Christmas To Me" from the new Pentatonix album of the same name. We've rounded up 15 of the best seasonal pop jams in the Apple Music playlist below, which even includes a few throwbacks you may have forgotten about from Hanson and 'NSYNC.

So dig out your Santa cap, unwrap a mini-candy cane and get into the spirit with Y2K-era Britney Spears. Tell us which pop gems you consider holiday staples, and if we left a particularly crucial one of the list, let us know!
