Good Sign is a song written by Lasse "Yogi" Anderson and Swedish singer Emilia Rydberg, and recorded by Emilia on her 1998 album Big Big World. The single was released on 7 December 1998 as the follow-up to her very successful debut-single "Big Big World". It peaked at number 16 in Sweden. Additionally it was a top 30 hit in Belgium, France and Switzerland and a top 40 hit in Austria. In the UK, "Good Sign" peaked at number 54.
AllMusic editor Roxanne Blanford described the song as a "uptempo celebration of life, delivered with sincerity and an engagingly happy sing-along chorus." The Daily Vault's Christopher Thelen wrote that Emilia's vocals on "Good Sign" are "powerful without being overbearing", adding that a "solid beat (even though a lot of it is synthesized), matched with some well-placed Vocoder lyrics is evidence enough that Emilia has a reasonable shot at stardom." Chuck Campbell from Knoxville News Sentinel said that the singer offers "an uplifting bit of reggae-tinged light R&B". Larry Printz from The Morning Call declared it as "Swedish pop in the ABBA/Ace of Base tradition."
