"Nothing Compares 2 U" is a song written and composed by Prince for his side project, The Family; the song featured on their eponymous 1985 debut album. The song's lyrics explore feelings of longing from the point of view of an abandoned lover.
In 1989, Irish singer Sinéad O'Connor recorded a version of the song for her second studio album, I Do Not Want What I Haven't Got (1990).
It was released as the album's second single in early 1990 and became a worldwide hit. O'Connor co-produced the record with Nellee Hooper, and its music video, directed by John Maybury, received heavy rotation on MTV. In December 1990, Billboard named "Nothing Compares 2 U" as the "#1 World Single" of 1990 at its first Billboard Music Awards.
Prince released his own rendition of "Nothing Compares 2 U", with Rosie Gaines on guest vocals in 1993. This live version of the song was included on his compilation album The Hits/The B-Sides.
His original 1984 studio recording of the song was eventually released in 2018 as a single and later on the 2019 posthumous compilation Originals.
