‘Mistletoe and Wine’ should be banned throughout the universe! Worst Christmas song ever.
I do always like hearing carols, but alas they hardly ever play those in shops - or if they do, they’re mucked-about pop versions, with one of those either breathe-y or screechy singers, and twiddly bits added. Those really do bring out my inner grumpy old bag, or rather my inner Scroogette at this time of year.
Contrary to the OP, after such a rubbish year, I think quite a few people are making a bit more of Christmas than usual, to make up for it.
Having said that, nobody ever has to go mad, over-indulge with food, presents or anything else. Plenty of people who enjoy Christmas (not the Bah Humbug brigade, obviously) manage to have a lovely time without going OTT.
I've got another 'keen'... Ouch!
