any Amy Grant Christmas album- I grew up on these! Listening to her rendition of "It's the Most Wonderful Time of the Year" brings back memories of the days I tried to plan, choreograph, direct, and publicize special Christmas shows performed by my siblings and I.
Michael Buble- He has such a beautiful voice, and the jazzy additions to popular songs like "Jingle Bells" give the album an old-fashioned classy feel.
most Sufjan Stevens Christmas EPs- Sufjan makes so much music! He has hours upon hours of Christmas music. Some songs are lovely covers, some are originals, and some are a mix of both. His originals are very interesting, and most often seem to challenge the materialism of Christmas.
Justin Bieber's Under the Mistletoe- It's just so fun! I can't deny the Biebs's melodic flow on this album. His "All I Want For Christmas (Superfestive!)" duet with Mariah Carey is indeed superfestive-- you can't help but try to sing along and serenade the person, plant, or piece of chocolate in nearest proximity.
DISCLAIMER! It is REALLY hard to pick favorite Christmas songs because they're all so nice to listen to. That said, I tried.
The Christmas Waltz- I feel like this is an all-encompassing classic song to reminisce of Christmases past and remember to take advantage of the season to tell people how much you love them.
Joy to the World- I love how um, joyful this song is! Hallelujah! Jesus has come to the world!
Christmas Time is Here- I could talk about how great A Charlie Brown Christmas is for a long time, and I'll probably do that later. I love it so.
Evergreen by Switchfoot- This song expresses a longing to be like an evergreen tree by living all year around and suggests that Jesus is the only way to feel "evergreen". It is definitely worth a listen or two.
I hope that my favorites of Christmas music are able to freshen up your December playlist!
