38. Frankie Goes To Hollywood: 'Relax' (1983) - One of the most controversial songs of the 80s, the decadent 'Relax' cover suited it perfectly. Featuring a male and female figure, apparently in bondage gear and tied together, the cover continues the S&M theme of the video. Although relatively mild by today's standards, the sleeve provides the perfect accompaniment to the sexual lyrical content of the single.
