I'm going to give this song a 5 star review just to counterpoint the previous reviewer's rant that's an unfair rating and has nothing to do with the song itself.
As for the song, it's a decent upbeat and catchy Christmas tune that will likely find its way on to future Christmas compilation albums. It's also significantly better than a lot of the other monotonous drivel that passes for pop music (One Direction I'm looking at you).
