Los Angeles, June 4 : Singer-songwriter-record producer Mariah Carey has been accused of plagiarism as a country music songwriter has claimed copyright infringement over 'All I Want For Christmas Is You'. Mariah and co-writer Walter Afansieff are named in the lawsuit by songwriter Andy Stone, who claims his 'All I Want For Christmas Is You' by Vince Vance & the Valiants from 1989 is being infringed, reports 'Deadline'. Stone filed his papers in the US District Court in the Eastern District of Louisiana. While the songs have the same title, there is only a hint of Mariah's melody or lyrics beyond the title call-out. Her version of the song came out in 1994 and has become a holiday staple on radio, streaming, and the NBA's annual slate of games on Christmas Day. As per 'Deadline', Stone claims his song received extensive airplay during the 1993 holiday season. He is asking for $20 million in damages. Stone claims Mariah and Afansieff "intentionally engaged in a campaign to infringe" his copyright on the work. Pamela Koslyn, a Los Angeles attorney specialising in music and intellectual property rights, noted there are 177 works, many of them musical compositions, with 'All I Want For Christmas Is You' as the title. Koslyn noted that she would have a different answer if all of the lyrics are "substantially similar" to Carey's version. Koslyn said in a statement accessed by 'Deadline': "Song titles aren't entitled to copyright protection. That's why there are 177 works using the same title. An even more popular title is 'My Baby', which has 4860 works registered with the Copyright Office. And that doesn't even count 'common law' (unregistered) works using the same title." The Mariah Carey version of the song has over 1 billion streams on Spotify alone. Last year, it became the first song to be a No. 1 hit in three separate runs on the Billboard Hot 100 Singles chart. /IANS
