Mariah Carey is an American singer, songwriter, record producer, actress, entrepreneur, and philanthropist. She was signed to Columbia Records in 1988 and rose to fame after releasing her eponymous debut album two years later. Carey is the first artist in history to have their first five singles become consecutive number one songs on the Billboard Hot 100. Renowned for her five-octave vocal range, melismatic singing style, and signature use of the whistle register, Carey is referred to as the "Songbird Supreme" by Guinness World Records.
In 1993, Carey married Sony Music head Tommy Mottola. She achieved worldwide success with follow-up albums Music Box, Merry Christmas, and Daydream. These albums spawned some of Carey's most successful singles, including "Hero", "Without You", "All I Want for Christmas Is You", "Fantasy", "Always Be My Baby", as well as "One Sweet Day", which topped the US Billboard Hot 100 for 16 weeks and became Billboard's Song of the Decade. After separating from Mottola, Carey adopted a new image and incorporated more elements of hip hop into her music with the release of Butterfly and Rainbow.
