Controversy is Prince's 4th album, released October 14, 1981. For the most part, the album was an expansion of its predecessor, 1980's Dirty Mind. The title track is a funk workout, where Prince seems to be bored of the media attention he was receiving. "Do Me, Baby" is a classic Prince ballad, with falsetto whoops and camp outbursts peppering the track. "Private Joy" is an upbeat, synthesizer romp layered with saucy innuendo. "Let's Work" is a highlight, based on a funky bass line with a stripped down synth-funk sound, foreshadowing Prince's next album, 1999. "Annie Christian" is an odd political number with sinister lyrics. The album finishes with the rather crude rockabilly ode to mutual masturbation, "Jack U Off." This record was considered to be his most political to date. The album was also an important stepping stone from his early works to the more mature song writing of the mid 1980s.
