"Vogue" - Madonna (May 19 - June 2, 1990) :
“Vogue" is one of Madonna’s biggest hits, and in 1990 it bumped Sinead O’Connor’s "Nothing Compares 2 U" from the number 1 spot on the Billboard Hot 100 chart. The dance-pop hit was originally recorded as a B-side track for Madonna's single "Keep It Together," off her Like A Prayer album. However, after the song was shared with executives it was decided to be too good for a B-side, and was instead added to here album "I'm Breathless : Music from and Inspired by the film Dick Tracy." The decision proved to be a smart move, as the single reached number 1 in over 30 countries and became the best-selling single of 1990.
