I have dark, bitter, cliched feelings about Christmas, so my favorite holiday song is, inevitably, the Pogues' "Fairytale of New York": https://www.youtube.com/watch?v=j9jbdgZidu8.

ETA: thanks for the comm recommendation! I got distracted by a problem with my computer speakers (bad wire, ugh) and forgot to look till just now. Somebody just posted a link to Sister Rosetta Tharpe's "Didn't It Rain," which is enough to sell me on the members' good taste right there. I remember the first time I heard her voice and how I sat up and took notice.
