This study examined the relationship between sexual content in music and sexual cognitions and risk among emerging adults in the United States and Australia. Music content was examined via lyrics, music videos, and social media posts of popular music artists. It was hypothesized that there would be a positive association between sexual content in music and sexual cognitions and risk. Sexual content in music lyrics, videos, and social media was assessed using content analysis of the top artists rated by participants in the United States and Australia. Findings indicated variations in sexual content based on music genre and location, and that music lyrics, videos and social media posts all contain sexual content. Results from hierarchical regression analyses indicated that sexual lyrical content, sexual content in music videos, and sexual references in the social media posts of artists were related to negative sexual cognitions for both samples. This trend was also found for the degree of sexual risk for both samples. While findings point to the direction of a universal impact of the association between sexual content in music and sexual cognitions and degree of sexual risk, they also highlight trends in these relationships across countries..

Charles Darwin wrote in a letter to his friend Asa Gray that “…the sight of a feather in a peacock’s tail, whenever I gaze at it, makes me sick!” Darwin was worried that the peacock’s tail couldn’t possibly help in its survival, and thus could be construed as evidence against his grand theory of evolution by natural selection..
