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.

Stripping away the hype, this book describes how, when, and why media violence can influence children of different ages, giving parents and teachers the power to maximize the media's benefits and minimize its harm. There are many opinions about media violence and children, but not all are supported by science. In this book, the top experts gather the latest results from 50 years of scientific study as the basis for a comprehensive, in-depth examination of the complex issues surrounding the effects of media violence of different types. Each chapter focuses on a particular issue of concern, including "hot" topics such as brain development, cyber-bullying, video games, and verbal aggression. Articles take into account factors such as economics, differences based on the ages of children, and differences between types of media violence. This book provides the information parents and those who work with families need to make the best choices. It includes chapters specifically relevant to the types of bullying schools have the most trouble identifying and controlling. Most importantly, the writing is both intelligent and accessible so that parents, educators, pediatricians, and policymakers can understand and apply the findings presented.

This paper presents the results of a content analysis of alcohol and drug portrayals in the top 100 Billboard songs from each of the years 1968, 1978, 1988, 1998, and 2008, thus allowing both a characterization of substance portrayals in music generally and an analysis of changes over time. Of the final sample of 496 songs, 10.3% contained a reference to alcohol and 5.7% contained a reference to drugs. A substantial increase was found over the decades, and in particular over the last two: in 1988, 12% of songs referred to either or both classes of substance, compared to 30% in 2008. Marijuana was by far the most frequently mentioned drug. Both alcohol and drugs were much more likely to be portrayed positively than negatively, especially in recent decades. The results are discussed in terms of relevant theories of media processing and impact.

In this article, the continuity in music taste from parents to their children is discussed via a multi-actor design. In our models music preferences of 325 adolescents and both their parents were linked, with parental and adolescent educational level as covariates. Parents' preferences for different types of music that had been popular when they were young were subsumed under the general labels of Pop, Rock and Highbrow. Current adolescent music preferences resolved into Pop, Rock, Highbrow and Dance. Among partners in a couple, tastes were similar; for both generations, education was linked to taste; and parental preferences predicted adolescent music choices. More specifically, the preference of fathers and mothers for Pop was associated with adolescent preferences for Pop and Dance. Parents' preferences for Rock seemed to indicate their daughters would also like Rock music, but not their sons. Parental passion for Highbrow music was associated with Highbrow preferences among their children. It is concluded that preferences for cultural artifacts such as (popular) music show continuity from generation to generation.
