Every music star needs to make a Christmas song to stay relevant at least once a year until the end of time. Ed Sheeran is no fool and teams up with Sir Elton John to yoddle out a holiday tune that will surely enchant us, then annoy us for the next few weeks. A good Christmas song could become it's own industry if done right like Mariah Carey and her All I Want for Xmas empire. So best of luck with your xmas ditty Elton and Ed, I'm sure we'll all love it actually!
