Mariah Carey is an American singer, songwriter, record producer, actress, and philanthropist. Under the guidance of Columbia Records executive Tommy Mottola, Carey released her self-titled debut studio album Mariah Carey in 1990; it went multi-platinum and spawned four consecutive number one singles on the U.S. Billboard Hot 100 chart. Following her marriage to Mottola in 1993 and success with hit records Emotions , Music Box , and Merry Christmas , Carey was established as Columbia's highest-selling act. Daydream made music history when its second single "One Sweet Day", a duet with Boyz II Men, spent a record sixteen weeks on top of the Billboard Hot 100, and remains the longest-running number-one song in U.S. chart history. During the recording of the album, Carey began to deviate from her R&B and pop beginnings and slowly traversed into hip hop.
