A country singer named Andy Stone is contesting the copyright of Mariah Carey’s hit "All I Want For Christmas Is You." The songwriting plaintiff is positing that the pop singer's hit caused brand confusion with a song he co-wrote prior to the release of her holiday favorite — though the songs share very little in common other than the title. Stone is seeking $20 million in damages from the pop icon, a fraction of the $60 million Carey reportedly has made of the song.
