Mariah Carey is an American singer, songwriter, record producer, and occasional actress. She rose to prominence after releasing her self-titled debut studio album Mariah Carey in 1990; it went multiplatinum and spawned four consecutive number one singles on the U.S. Billboard Hot 100 chart. Under the guidance of Columbia Records executive and later husband Tommy Mottola, Carey continued booking success with followup albums Emotions (1991), Music Box (1993), and Merry Christmas (1994), and was established as Columbia's highest-selling act. Daydream (1995) 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. This musical change became evident with the release of Butterfly (1997), at which time Carey had separated from Mottola.
