"The Sign" is a 1993 dance-pop song by the Swedish band Ace of Base. The song was an international hit, reaching Number two in the United Kingdom and spending six non-consecutive weeks as number one on the Billboard Hot 100 chart in the United States. (It was the first single to have two distinct runs at #1 since Men at Work's "Down Under" in 1983; the 582-week gap between their second runs is the longest such in Billboard history.) It was on an album called Happy Nation in most of the world, but The Sign in North America.
The song was the #1 song of 1994 according to Billboard magazine's year-end charts. The song was ranked at #51 on The Billboard Hot 100 All-Time Top Songs for the first 50 years of the Hot 100 chart.
The song has been covered by The Mountain Goats, and was also heavily featured in the fifth season finale of American Dad!, "Great Space Roaster".
