You might just be getting old. Researchers have found the music of today is, for instance, more focused on terms like "I" and "me" than "we" and "us." The trend has been steadily increasing since the 1980s, and psychologists Keith Campbell of the University of Georgia and Jean Twenge of San Diego State University have examined the phenomenon using several decades worth of stats from the Narcissism Personality Inventory. The test uses queries like "I try not to be a show-off" and "I will usually show off if I get the chance" to determine a subject’s self centeredness. Campbell and Twenge found the rise in narcissism, particularly in "young people."
