After a computer analysis of three decades of hit songs, psychologist Dr.Nathan DeWall and others report finding what they were looking for: a statistically significant trend toward narcissism and hostility in popular music. As they hypothesized, the words “I” and “me” appear more frequently along with anger-related words, while there’s been a corresponding decline in “we” and “us” and the expression of positive emotions.

“Late adolescents and college students love themselves more today than ever before,” Dr. DeWall, a psychologist at the University of Kentucky, says. His study covered song lyrics from 1980 to 2007 and controlled for genre to prevent the results from being skewed by the growing popularity of, say, rap and hip-hop.

Defining the personality of a generation with song lyrics may seem a bit of a reach, but Dr. DeWall points to research done by his co-authors that showed people of the same age scoring higher in measures of narcissism on some personality tests. The extent and meaning of this trend have been hotly debated by psychologists, some of whom question the tests’ usefulness and say that young people today aren’t any more self-centered than those of earlier generations. The new study of song lyrics certainly won’t end the debate, but it does offer another way to gauge self-absorption: the Billboard Hot 100 chart. The researchers find that hit songs in the 1980s were more likely to emphasize happy togetherness, like the racial harmony sought by Paul McCartney and Stevie Wonder in “Ebony and Ivory” and the group exuberance promoted by Kool & the Gang: “Let’s all celebrate and have a good time.” Diana Ross and Lionel Richie sang of “two hearts that beat as one,” and John Lennon’s “(Just Like) Starting Over” emphasized the preciousness of “our life together.”

Today’s songs, according to the researchers’ linguistic analysis, are more likely be about one very special person: the singer. “I’m bringing sexy back,” Justin Timberlake proclaimed in 2006. The year before, Beyoncé exulted in how hot she looked while dancing — “It’s blazin’, you watch me in amazement.” And Fergie, who boasted about her “humps” while singing with the Black Eyed Peas, subsequently released a solo album in which she told her lover that she needed quality time alone: “It’s personal, myself and I.”
