Is there anyone this year who isn't covering "All I Want for Christmas Is You" by Mariah Carey?

Justin Bieber did it, a group of UK sailors did a Mimi-approved lip-dub of it, some very skilled dancers choreographed a killer routine to it -- and now, "Glee" is stepping up to the plate.

The TV show is the latest to unveil its version of the 1994 song, with Amber Riley's "Mercedes" belting out all the holiday high-notes.

For fans of Sam/Mercedes as a couple, keep an eye out for the cute moment they share mid way through the song. Could Tinker be getting the boot?

How do you think this version holds up against the original?

The cast is also covering Band Aid's 1984 hit, "Do They Know It's Christmas?" -- and donating 100% of the proceeds to Band Aid Trust, an organization that supports projects designed to make a lasting difference in Ethiopia, Somalia and surrounding countries in East Africa.

Watch that performance here.
