Not sure what's it like elsewhere but lot of shops in London start playing really bad christmas muzak pretty much from early Dec. Ghastly.
I've got a CD of classical Christmas stuff which makes 4 nice ring the changes. Stuff like Lt Kije. As for 'classic' xmas tunes, I'll second Kitt's Santa Baby
, Garland or Nat King Cole's 'Have Yourself...'
(am I the only one who finds that tune really
melancholy and sad? - not good for depressives) and Let It Snow/Jingle Bell Rock
, which always make me think of Die Hard
