Mariah Carey is an American singer, songwriter, actress, record producer, and entrepreneur. Referred to as the "Songbird Supreme" by the Guinness World Records, she is noted for her five-octave vocal range, melismatic singing style, and signature use of the whistle register. She rose to fame in 1990 after signing to Columbia Records and releasing her eponymous debut album, which topped the U.S. Billboard 200 for eleven consecutive weeks. Soon after, Carey became the only artist ever to have their first five singles reach number one on the U.S. Billboard Hot 100 chart, from "Vision of Love" to "Emotions".
Following her marriage to Sony Music head Tommy Mottola, Carey 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 became the longest-running U.S. number-one single in history. After separating from Mottola, Carey adopted a new image and incorporated more elements of hip hop into her music with the release of Butterfly.
