Creating a playlist of the least popular Christmas songs can be a bit subjective, as it depends on personal taste. However, here are some songs that often appear on "least favorite" lists:

1. "Christmas Shoes" by Newsong
2. "Santa Claus Has Got the Sniffles" by The Kiboomers
3. "I Saw Mommy Kissing Santa Claus" by Jimmy Boyd
4. "Grandma Got Run Over by a Reindeer" by Elmo & Patsy
5. "Please, Daddy (Don't Get Drunk This Christmas)" by John Denver
6. "I Want a Hippopotamus for Christmas" by Gayla Peevey
7. "Santa Baby" by Madonna
8. "Dominick the Donkey" by Lou Monte
9. "All I Want for Christmas Is My Two Front Teeth" by Spike Jones & His City Slickers

Remember, music is subjective and everyone's tastes are different. What one person might find annoying, another might find charming or nostalgic!
