Music may be the best way to put you into the holiday mood, but hearing the same Jingle Bells and Rudolph the Red-nosed Reindeer carols at your door can be tiring. These Christmas favorites, however, still manage to stay fresh throughout the season -- you'll never get tired of hearing them over and over again.

Check out our favorite picks for our Christmas playlist to keep on loop.

Idina Menzel and Michael Buble -- "Baby it's Cold Outside"

The video of this classic Christmas cover went viral featuring adorable pre-teens in the roles of Idina and Buble in elegant flapper style.

Zooey Deschanel and Joseph Gordon-Levitt -- "What are You Doing New Year's Eve?"

Not really a Christmas song, but this one still manages to put you in a romantic, holiday mood. And who can resist the cuteness of Zooey and JGL singing with their ukeleles?

Pentatonix featuring Tori Kelly -- "Walking in a Winter Wonderland"

This a capella band has been taking the Internet by storm ever since they won the third season of The Sing-Off. Check out their instrument-less rendition of this holiday classic mashed up with a decidedly more summery, cheery tune to keep you chipper and warm.

John Lennon and Yoko Ono -- "Happy Xmas (War is Over)"

This song from 1970 has often been called the "greatest Christmas record ever made." It certainly continues to pull at our heartstrings and its message still remains true and relevant even today.

Nat King Cole -- "O Come All Ye Faithful"

Cole's smooth voice never fails to fill our hearts with all the fuzzies, reminding us of the true meaning of Christmas.

Mariah Carey -- "All I Want for Christmas Is You"

No Christmas playlist is complete without the whistling notes of Mariah at her peak.

Band Aid -- "Do They Know it's Christmas"

Finally, the ultimate celebrity-filled Christmas song for a cause. Featuring the greats: Stevie Wonder, George Michael, Sting, Bono, Phil Collins, Boy George, and many others who united their voices in support for Africa.

As a bonus, here is the 2014 remake of the iconic Do They Know it's Christmas, featuring some of the artists from the original, such as Bono, and some new pop artists on the scene who wanted to repeat the success of the 1984 record in order to support the victims of ebola in West Africa.
