What has America been singing about? Trends in themes in the U.S. top

This study explored 19 themes embedded in the lyrics of 1,040 U.S. top-40 songs from 1960 through 2010, using R strucchange software to identify trends and breaks in trends. Findings reveal both continuity and change. As in 1960, the predominant topic of pop music remains romantic and sexual relationships. However, whereas the proportion of lyrics referring to relationships in romantic terms remained stable, the proportion including reference to sex-related aspects of relationships increased sharply. References to lifestyle issues such as dancing, alcohol and drugs, and status/wealth increased substantially, particularly in the 2000s. Other themes were far less frequent: Social/political issues, religion/God, race/ethnicity, personal identity, family, friends showed a modest occurrence in top-40 music throughout the studied period and showed no dramatic changes. Violence and death occurred in a small number of songs, and both increased, particularly since the 1990s. References to hate/hostility, suicide, and occult matters were very rare. Results are examined in the context of cultural changes in the social position of adolescents, and more specifically in light of the increased popularity of rap/hip-hop music, which may explain the increases in references to sex, partying, dancing, drug use, and wealth
