Madonna moved in with boyfriend John "Jellybean" Benitez, asking his help for finishing the album's production. Benitez remixed most of the tracks and produced "Holiday", which was her third single and her first global hit. The overall sound of Madonna was dissonant and in the form of upbeat synthetic disco, using some of the new technology of the time, like the Linn drum machine, Moog bass and the OB-X synthesizer. The album was released in July 1983 and peaked at number eight on the Billboard 200 six months later, in 1984. It yielded two more hit singles, "Borderline" and "Lucky Star".
