The most distinctive development in the aesthetics of music in the 20th century was that attention was directed at the distinction between 'higher' and 'lower' music, now understood to align with the distinction between art music and popular music, respectively. Theodor Adorno suggested that culture industries churn out a debased mass of unsophisticated, sentimental products that have replaced more 'difficult' and critical art forms that might lead people to actually question social life. False needs are cultivated in people by the culture industries. These needs can be both created and satisfied by the capitalist system, and can replace people's 'true' needs: freedom, full expression of human potential and creativity, and genuine creative happiness. Thus, those trapped in the false notions of beauty according to a capitalist mode of thinking can only hear beauty in dishonest terms (citation necessary).
