O’Connor reached international fame with her 1990 album I Do Not Want What I Haven't Got, which contained the cover of Nothing Compares 2 U, a song written by Prince. She received Grammy nominations for Record of the Year and Best Female Pop Vocal Performance, and eventually won for Best Alternative Music.

O’Connor was criticized when she went on Saturday Night Live in 1992 when she ripped up a photo of Pope John Paul II in a protest of the sexual abuse within the Roman Catholic Church. O’Connor has been relatively outside of the media spotlight for several years.
