The idiot that waited 28 years to file a lawsuit, which will be thrown out. There are 177 copyrighted works titled “All I Want For Christmas Is You,” many of them musical compositions. Source: Billboard.

Many of Mariah's greatest hits were written by her and just one collaborator (#1's Vision of Love, Someday, Can't Let Go, Hero, Love Takes Time, My All, All I Want for X-Mas, Dreamlover, I Don't Want to Cry, etc.).

It wasn't until she delved into hip-hop that she began writing with a larger group of collaborators, but still NOWHERE near the size of the song-writing armies that The Weeknd, Kayne, Justin B, Katy Perry, etc. bring in.
