Grounded in more than a decade of field research, this book uses empirical examples, quantitative data, and qualitative interviews with young music consumers as well as music industry professionals to understand how the platforms behind music production, distribution and listening work in our digital society. Bringing together the perspectives from science and technology studies, media studies, and the political economy of digital platforms, the book outlines the process of mutual construction between music digital platforms and the cultural value of music in today's society, and also reflects on the complicated relationship between the power of platforms and the agency of listeners.
