My favorite is "I Wish It Could Be Christmas Everyday", because my dad liked it and we always played it while decorating the tree when I was little. It brings back nice, happy childhood memories.
Least favorite by a mile is "Stay Another Day", which is a simp anthem disguised as a Christmas song, and then "All I Want For Christmas Is You" which is excruciating. Actually, I might overrule that and say I hate "Santa Baby" more, because it's just a gold digger begging for gifts.
Love: White Christmas, such an amazing song. Hate: Most of it has been mentioned already except one: Last Christmas, I hate this song with a burning passion, it's not a Christmas song.
Die Hard is more of a Christmas movie than Last Christmas is a Christmas song.
Die Hard is a great Christmas movie though
