This article explores the concept of music discovery and seeks to provide a definition of the act of discovering music content. Research on music consumption has weakly theorized what the moment of “discovery” consists of, since it has been more preoccupied with debates about the conditions of discoveries, which either highlight the importance of individuals’ social milieus or the enhanced technological agency that they enjoy in the digital age. Drawing on qualitative data about musical experiences, this article frames discoveries as affective responses to music content that occur within individuals’ life narratives and mediate their interpretation and definition of music.
