#1's as part of a four-album agreement with Sony Music to terminate her contract with then-label, Columbia. Sony wanted to release an album that featured her US number-one singles, void of any new material. However, Carey felt that not including any new material would be unfair to fans, and eventually four new songs were included to accompany her thirteen number ones. Writing and composition The first of Carey's number ones to be featured on the album was "Vision of Love". It was Carey's first single and was the song that propelled her into the music scene. The song received acclaim, and was credited with influencing and popularizing the use of melisma throughout the 1990s. Three other songs were included from her self-titled debut album, of them were "Love Takes Time", "Someday" and "I Don't Wanna Cry".
