Christmas songs I like, and I am a sucker for Christmas songs, by the way:
Whichver that one that Shakin' Stevens did. No, really.
Elton John - Step Into Christmas
The Pogues - Fairytale Of New York (obviously. The greatest Christmas song of all time)
My own Christmas song, 'A Very Cheesy Christmas,' a deliberately shit, ironic Christmas instrumental that I'm actually quite proud of.
Blink 182 - Happy Holidays You Bastard
Blink 182 - I Won't Be Home For Christmas
