Christmas songs pop up all year round, by band you'd never expect they'd write one. Here are four fairly recent alt-rock songs about Christmas (that don't make 'm Christmas songs, if you catch my drift). She Came Home For Christmas by Danish band Mew is my favourite, a dreamy track with furiously crashing guitars in the middle. The Ocean Tango (a French/Swedish project) are dreamy as well, in a Carpenters-y style. Russian Futurists are funny Canadians, 100 Shopping Days 'til Christmas is a funny title for a song. Centro-Matic and South San Gabriel are Americana-bands, Christmas '83 appeared on a collaboration-EP.
UPDATE: (from the comments:) It's actually a Centro-Matic song... as it was originally released via Stereogum 2 years ago. South San Gabriel is actually fronted by the same guy who fronts Centro-Matic... so it's hard to call it a collaboration. Sorry to get all geeky.
