Roxette - It Must Have Been Love

"It Must Have Been Love" is a song written by Per Gessle and performed by the Swedish pop duo Roxette. It was released on December 2, 1987. The song gained even greater success with a slightly edited version, which omitted the Christmas references and was created for the soundtrack of the 1990 film Pretty Woman. This power ballad became the duo's third number one hit in the United States, reaching the top spot on the Billboard Hot 100 on June 16, 1990, where it remained for two weeks.
