Economic, cultural, social, and political life is being increasingly shaped by digital platforms including social networking sites (Facebook), streaming services (Netflix) and sharing platforms (AirBnB). While social scientists have tracked the rapid emergence of platforms and developed useful conceptualisations about what they are and how they operate, surprisingly little attention has been paid to the nature of platform competition or the experiences of users. To address these gaps, this paper focuses on the illustrative case of recorded music, where platforms, including Spotify and Apple Music, face intense competition due to similarities in price and content. Drawing on 42 semi-structured interviews, 20 app 'walk-alongs' with Spotify users and an analysis of 120 documents (industry reports, trade magazines, press releases and news articles), it demonstrates how the basis of competition has shifted from content, price and curation to the engineering of compelling experiences that harness the unique and interconnected affordances of platformisation. The paper nuances our understanding of the dynamic and contingent nature of platforms, the processes of datafication and curation underpinning their interventions in markets and everyday life, the geographies of these virtual distribution and consumption channels, and the ways in which users imagine, value, and experience music streaming platforms.
