1) Damien Jurado released a new, so sad song called "Kalla Hus."
2) Sea Navy has a new song, too. It's called "Christmas Confession," and when you download it off Bandcamp for a $1, they'll give the money to toysfortots.org. Nice!
3) I can't believe I've neglected to mention this until now, but John Roderick and Jonathan Coulton have a whole album's worth of holiday cheer called One Christmas at a Time, which you can preview and buy here. (They even have an "ugly sweater" t-shirt for sale, for those who want to take their holiday cheer to the next level.)
