I find it a period of mixed emotion. Sometimes you can put your knife and fork into turkey breast and wonder why you are indulging like this. Sometimes it's coincided with my own periods of other trouble. Probably, more generally, I think we can ponder how commercial so much of it seems to be.
Of course songs, even chart songs can hold memories. I'm (in terms of popular music - I was born in 1960) a late 60s/70s child so if you did want to go Christmas Songs, even Slade and the days of Glam Rock have memories...
