I don't know that the songs I hear at Christmas remind me of anything specific. A lot of them I didn't know until only a few years ago when radio stations started playing all Christmas music for an entire month. They're just feel-good songs, except for the ones that aren't. Those that don't sound like Christmas songs don't generally make me feel good. Other new songs remind me of situations when I heard them and do bring back good memories, ana amazingly those don't have to be songs I actually like, or that seem to me to be Christmas songs.Problem with doing something like that on radio is that Christmas programming works as it's a major holiday, people decorate and bake and shop and celebrate at work sometimes for weeks leading up to it, and carols remind them of their childhoods, spending time with friends, loved ones and relatives maybe no longer with us, where Halloween programming isn't really sentimental at all and is mostly song parodies and frivolity. Not exactly the same.
Songs about Christmas do not qualify. They have to be songs that seem like Christmas songs, and no, sleigh bells or other sound effects with adult contemporary music won't get it done.
