The only Xmas songs I like are.
Shakin Stevens - Merry Christmas Everyone
Chris De Burgh - A Spaceman Came Travelling (not really a Xmas song though)
Frankie Goes to Hollywood - Power Of Love
The latter reminds me of my late mum as she used to love it, she died the week before Xmas and it was the first song I heard after she passed so I usually get a bit emotional when I hear it.
