.....The Sign by Ace of Base. Looking back, maybe Ace of Base was a total cheeseball, but you gotta admit they had some catchy-ass songs. The Sign hit #1 on March 12, 1994, knocking Celine Dion's Because You Loved Me off the top spot, spent four weeks at the top, lost the position to Bump n' Grind by R. Kelly for two weeks and then took #1 again for an additional two weeks. People REALLY liked this song, you guys. You know, not me. But OTHER people. The Sign went on to become the #1 single of 1994, the #11 single of the decade, and when Billboard released their top 100 songs of their first 50 years, The Sign was #51 of all the songs in Hot 100 history. Dayum! Not to shabby for a band that is basically an imitation, up-to-date ABBA. Anyway, sit back, relax and try not to bob your head along to this 90s gem. Here is the #1 song from 21 years ago today, The Sign by Ace of Base.
