"Sign o' the Times" (stylized as "Sign "☮︎" the Times") is the lead single from American musician Prince's 1987 album of the same name.
Despite being negative in nature, the song was originally intended for two separate Prince albums meant to be released in 1986, that were both shelved: Dream Factory and Crystal Ball. (Many of the tracks from both of these albums ended up on the album Sign o' the Times.) Prince performed all vocals & instruments on the song.
"Sign o' the Times" was reportedly written and composed on a Sunday, when Prince usually wrote his most introspective songs.
The song proved popular upon release, topping the R&B chart, and reaching number three on the Billboard Hot 100 and number 10 on the UK Singles Chart.
In 2010 Rolling Stone ranked "Sign o' the Times" at number 304 on their list of the 500 Greatest Songs of All Time. By July 1987, it sold 200,000 copies in the United States.
In 1987, Village Voice's Pazz & Jop critics' poll named "Sign o' the Times" the best single of the year, Prince's third recognition in that category.
The song is also included in The Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. Cat Glover is pictured on the single hiding her face behind a black heart.
