In 1997, Amil was involved with an all-female group called "Major Coins". The group met Jay-Z, who was looking for a woman to provide vocals on his third album, Vol. 2... Hard Knock Life. The part for the female rapper was really for her friend, but when Jay-Z asked Amil to freestyle and liked it, he decided to put her on the song instead. Amil, wanting to remain loyal to her friend, did not prefer to be put on the song, but Jay-Z allowed them both to do a version of the song.[2]
Soon after Major Coins broke up, Amil decided to follow a solo career with Jay-Z's label, Roc-A-Fella Records, joining the 1999 Hard Knock Life Tour. After the tour, she appeared on songs with Mariah Carey, Beyoncé, Jermaine Dupri, AZ, DJ Kay Slay, LL Cool J
