How many times do you think you'll hear 'All I Want For Christmas Is You' between now and December 25th? The chances are it'll be dozens - and feel like a whole lot more.
But for singer Mariah Carey, of course, it can't be often enough, as she's raking in the royalties every year.

But who are the biggest earners from Christmas songs?
PrezzyBox has an up-to-date Christmas Royalty Calculator, which comes up with a figure based on mechanical royalties, performance rights, synchronisation and even print music sales - combined with radio, online and TV data.
According to this reckoning, last year Slade's Noddy Holder and Jim Lea cleared more than £500,000 in royalties from 'Merry Christmas Everybody' - although this year it's looking a lot lower at a little over £105,000.

Meanwhile, the Pogues are reported to make more than £400,000 every year from their unconventional ballad 'The Fairytale of New York'.
And for some of these musicians, the money has been coming in a long time: while Brenda Lee's Mistletoe and Wine, for example, only makes around £5,000 a year, it's been bringing in the cash since 1962.
