Roxette – It Must Have Been Love

"It Must Have Been Love" is a song by Roxette that gained worldwide success in 1990 after being featured on the soundtrack of the film Pretty Woman. Originally released as a Christmas song in Sweden during the late 1980s, the ballad was later reworked with new lyrics to match the romantic atmosphere of the movie. Built around piano melodies, emotional vocals from Marie Fredriksson, and soft rock production, the song focused on lost love, memories, and emotional longing.
