'Tis the season for arguing about Christmas songs.

Some people like them, some people hate them, but pretty much everyone has an opinion about them.

And if there's one place that's absolutely perfect for thrashing out never-ending arguments, it's Twitter.

On Thursday, British TV presenter Richard Osman kicked off the latest in his ongoing series of poll-based Twitter competitions: The "World Cup of Christmas Songs 2017". Basically it's a knockout game in which a bunch of songs are arranged into groups, people vote for their favourite, and then the lowest-voted tracks are gradually whittled down until a winner is crowned.

80,000 votes later, though, and the two finalists had emerged: "Last Christmas" vs. "Fairytale of New York". A battle for the ages.

And there could only be one winner...

To be fair it's clearly the best Christmas song, isn't it? Was there ever any doubt?
