Mariah Carey sued for copyright over 'All I want for Christmas is You'

Singer Mariah Carey is being sued for copyright infringement over her 1994 Christmas mega-hit, All I Want for Christmas is You.

Songwriter Andy Stone says he co-wrote a song with the same name five years earlier, arguing that Carey exploited his "popularity" and "style".

Despite sharing a title, the two songs appear musically different, but Stone claims Carey caused confusion and did not ask for permission.

The BBC reports that Carey has not yet responded.

A must-have on any Christmas playlist, Mariah Carey's All I Want for Christmas is You is one of the best known Christmas records of all time.

Since appearing on the album Merry Christmas in 1994, it has topped the charts in several countries and by 2017 had reportedly earned Carey more than US $60 million in royalties.
