This book analyzes regulatory models established in the field of online music distribution, and examines their consistency with the overarching objectives of copyright law. In order to do so, the book takes a deep dive into the provisions of international treaties, EU Directives as well as the German and US copyright systems and case law. It subsequently scrutinizes the identified regulatory models from the standpoint of the copyright's objectives with regard to incentives, rewards, a level playing field, and dissemination. Lastly, it endorses the improved market-based statutory license as a preferable instrument in the online music field. The book is intended for all readers with an interest in music copyright law. Part I will especially benefit copyright scholars and practitioners seeking in-depth insights into the current legal situation regarding streaming and downloading. In turn, Part II will above all appeal to scholars interested in "law and economics" andin the theoretical foundations of online music copyright. Policy recommendations can be found in Part III.
