Incredible sums of money.
A good Christmas song has always been viewed as a nice pension with royalties rolling in once the Christmas season swings into action.
According to
Priceonomics, none more so that Mariah Carey's 'All I Want For Christmas Is You'. You may have heard it once or twice this month...
Since its release in 1994 it has accumulated $50m in royalties and is in the top 15 selling singles of all time.
It has actually sold 14 million units as a single since its release and the money generated is getting bigger each year.
