A University of Kentucky psychologist reviewed the lyrics of the top 10 songs from 1980 to 2007 and found evidence of our increasing narcissism. Pop music now includes more first-person singular pronouns (I, me, mine), while first-person plural pronouns (we, us, our) declined. Even words conveying positive emotions like “love,” “nice,” and “sweet” are decreasing in favor of words about anger like “hate,” “kill,” and “damn.” The researchers claims this mirrors “recent evidence showing increases in U.S. loneliness and psychopathology over time.”
