While "Little Red Corvette" helped Prince cross over to the wider rock audience, the rest of "1999" retains the funk elements featured in previous albums and is dominated by the use of synthesizers and drum machines. The album is, however, notable within Prince's catalogue for its wide variety of themes in addition to the sexual imagery which had already become something of a trademark on his previous work. "Automatic", extending to almost ten minutes, starts side three of the album with a prominent synthesizer melody and bondage-inspired lyrical imagery which, transplanted to the music video for the track (with a scene that depicted Prince being tied up and whipped by band-members Lisa Coleman and Jill Jones), had been deemed too sexual for MTV in 1983.
