O'Connor's take on Prince's song, the second single from her sophomore album I Do Not Want What I Haven't Got, brought the Irish performer worldwide acclaim. The song earned three Grammy nominations in 1990, and spent 21 weeks on the Billboard Hot 100, where it peaked at No. 1 in April that year.
The Prince estate released the late artist's previously unheard version of the original version on the song in April 2018, two days before the second anniversary of his death at age 57.
