Carey's debut album was released under the guidance of Columbia Records executive Tommy Mottola, whom she married three years later. Carey achieved further success with the albums Music Box (1993), Merry Christmas (1994), and Daydream (1995), with singles including "Hero", "Without You", "All I Want for Christmas Is You", "Fantasy", "Always Be My Baby", and "One Sweet Day", which topped the US Billboard Hot 100 decade-end chart (1990s). After separating from Mottola, Carey adopted a new image and incorporated more elements of hip hop with Butterfly (1997). Billboard named her the Artist of the Decade (1990s), while the World Music Awards honoured her as the best-selling female pop-artist of the millennium.
