Boxing day is my birthday, so I always enjoy 'happy b-day to me' by cracker, maybe i am biased. In a side note; I was introduced to soccer/football by a brit pretty much on boxing day. He took me to the only place in Sioux Falls open at 8am and willing to play soccer and serve beer, for my birthday. Arsenal, his team and subsequently mine (in your face Wheat!) won, so perhaps you can drub up a chorus of "there's only one MARK WHEAT!"

How 'bout these...(which are more a long the lines of a celebratory tone, rather than sleighbells etc)
Groovy Gravy-Quincy Jones
Wraith Pinned to the mist and other games-Of Montreal
Thank you Jack White-Flaming Lips
Let's Shake Hands-The White Stripes
Caravan-Van Morrison

Ummm. that's all I got right now. Maybe more later.

Arsenal?? Hmmmm...
Bebel Gilberto ~ Winter (Nuspirit Helsinki remix)
Manic Street Preachers ~ So Why So Sad ( you know, when you didn't get the gift you really wanted, afterall )
Queen Latifah ~ If You Don't Know (the "Happy New Year" intro!)
Galaxie 500 ~ Listen, The Snow is Falling
Simon & Garfunkle ~ The Boxer (heh heh....just kiddin'...maybe)

if you're "of an age", some beatles music may put you in a holiday mood. capitol and emi timed many of their early releases to take advantage of the holiday market.
