Popular music theory analyzes the genre from several perspectives including audience, composition, and how it relates to music videos and postmodernism. Approaches include sociological analysis of audiences and their representation, as well as queer theory influenced by artists like Madonna. In postmodernism, distinctions between reality and simulation have blurred, identity is fluid, and consumerism involves self-construction through copies without originals, as seen in popular music recordings and videos that lack authentic performances.
