Unlike the movie, the album Who's That Girl became an instant international smash hit, with the song Who's That Girl becoming a number one hit in the United States, England and Puerto Rico, among others. Another hit included in the album was Causing a Commotion, although Causing a Commotion, it could be said, was only a mild hit compared to the title song.
Although Madonna was the main star in the album and the album is generally considered to be one of Madonna's, it is actually a various artists album, because five other music acts participated in it.
