 The album , released before the film , sold a million copies in the United States , and five million worldwide . Taraborrelli felt that at that moment , riding on Madonna 's coattails proved profitable for everyone involved , including Warner Bros. Records , which notched up big sales with a compilation soundtrack album that was basically a showcase for its marginal artists . But still they wanted to " milk @-@ in " the success of Madonna , a view shared by Peter Guber and Jon Peters , executive producers of the film . Hence they felt a worldwide concert tour was the appropriate thing to do , since it would promote both the soundtrack and the film , as well as Madonna 's successful third studio album True Blue , released the year before . As Madonna 's first world tour , Who 's That Girl ended up being a resounding success , although by its end , Madonna declared that she did not want to hear any of her songs again and she did not know whether she would ever write another one . " I returned feeling so burned out and I was convinced that I wouldn 't go near music for quite a while " , she said .
