Sinéad O’Connor, the legendary Irish singer-songwriter best known for her hit cover of Prince’s “Nothing Compares 2 U,” has died, her family has confirmed. She was 56. The Irish Times also reported the news.

In a statement to Irish public service broadcaster RTE, the singer’s family announced: “It is with great sadness that we announce the passing of our beloved Sinéad. Her family and friends are devastated and have requested privacy at this very difficult time.”…

In her 35-year career, O’Connor sold millions of records and released one of the most famous music videos of all time. Yet she may best be remembered as one of pop’s most fearless voices, one who spoke openly about her personal struggles with mental health and abuse and never shied away from controversy with her uncensored, and at times unpopular, opinions. She routinely criticized the Catholic Church and its handling of sexual abuse accusations. In 1992, she tore up a photo of the Pope during her guest performance on Saturday Night Live, a move that dogged her career and her relationship with the media for the rest of her life.
