This book explores the nature of the music industries before and after the digital revolution from the point of view of the consumer. Opening an essential interdisciplinary dialogue across music studies, business, and law, it applies business model literature to antitrust law offering a comprehensive history of encounters between the music industry and antitrust and regulatory authorities in the US, UK, and EU. Considering the historically consolidated environment of the music industries, and their rapidly evolving business models in the 21st century, the author argues that there is a need for updated competition design to promote consumer welfare and competition in these markets.
