This book examines the collection and curation of music, and the way digital streaming services are transforming the way we engage with the media. The study foregrounds personal digital curation techniques, rather than algorithms or technology, to acknowledge the sustaining human agency involved in playlisting. The author looks at Digital Service Providers such as Spotify, Apple and Deezer, which offer their users not just access to large collections of music, but also the opportunity to create and maintain personalised consumption subsets such as playlists. Positioning these current playlisting practices as a remediation of significant cultural practices of the 20th century - such as collecting records and mix-taping - the book highlights the continuity of culture through media change, and the implications for concepts of self and identity, society and sharing. Shedding new light on this contemporary cultural phenomenon, this book will be an important read for scholars who are interested in the area of digital music from different disciplines such as communication, digital humanities and social sciences in fields of media studies, digital cultures, personal information management, digital curation and popular music.
