It would include two other number-one tracks, "What A Girl Wants" and "Come On Over Baby (All I Want Is You)."These were the singer's only solo chart toppers, though she would score another number one as part of an all-star girl group put together for the movie soundtrack song "Lady Marmalade.""Genie In A Bottle" took over number one from Will Smith's "Wild Wild West." After a four-week reign, the song was replaced by Enrique Iglesias' "Bailamos."
