The music of the 1970s often reflected changing philosophical interests compared to previous decades, with personal growth, private revelation, and self-improvement gaining more emphasis compared to past interests in collectivist social activism. The period coming to be known dismissively as the "Me Decade", rock releases frequently celebrated a hedonistic, self-indulgent abandonment. Multiple artists also pursued an arena rock sound based on individual inspiration and achievement, particularly in anthemic songs about independence. In terms of the changing trends into the 1980s and onward, the style essentially replaced disco in terms of mass pop culture appeal.
