Pretty Woman: It Must Have Been Love, Roxette
The movie: Pretty Woman
The song: 'It Must Have Been Love', Roxette
The Swedish duo put music to heartbreak with this heartfelt ballad, making it perfect for the bit in Pretty Woman where Vivian leaves Edward and heads back to her real life. Gulp. It is now on every break-up playlist ever made.
Bonus knowledge: Though Per Gessle was asked to write a song for the film, he was short on time and Roxette had already recorded this rather appropriate tune so he just handed it over. The big cheat.
