Mariah Carey is an American singer, songwriter, actress, and record producer renowned for her extraordinary five-octave vocal range, melismatic singing style, and use of the whistle register, earning her titles such as "Songbird Supreme" and "Queen of Christmas." Born on March 27, 1970, in Huntington, New York, she began singing at an early age and developed her signature vocal skills through formal lessons. Carey rose to fame with her self-titled debut album in 1990, which produced four consecutive No. 1 singles on the U.S. Billboard Hot 100, including "Vision of Love" and "I Don't Wanna Cry." Over her career, she has sold more than 200 million records worldwide, making her one of the best-selling music artists of all time[1][4][6]. She holds the record for the most No. 1 singles by a solo artist on the Billboard Hot 100, with 19 chart-toppers such as "Fantasy," "Always Be My Baby," and "We Belong Together"[4]. Throughout the 1990s, Carey evolved from pop and R&B into hip-hop-influenced music, especially after her separation from Columbia Records executive Tommy Mottola. Albums like *Butterfly* (1997) showcased this shift, and her duet "One Sweet Day" with Boyz II Men set a record for the longest-running No. 1 song in Billboard history with 16 weeks atop the chart[2][3]. Her career experienced challenges in the early 2000s, including a physical and emotional breakdown in 2001 and a commercially disappointing film and album (*Glitter*). However, she rebounded with *The Emancipation of Mimi* (2005), which became the best-selling album in the U.S. that year and earned multiple Grammy Awards[2][3]. More recently, her enduring holiday hit "All I Want for Christmas Is You" reached No. 1 on the Billboard Hot 100 in 2019, 25 years after its release, setting a record for longevity[5]. Carey continues to release music, with her 15th studio album *Caution* released in 2018 and her 16th album *Here For It All* announced for 2025[4][5]. She remains a prominent figure in music, celebrated for her vocal talent and lasting impact on pop and R&B genres.
