Using the music of the Final Fantasy game series as our case study, we follow the music through processes of transmediation in two very different contexts: the Netflix series Dad of Light and music transcription forum Ichigo’s Sheet Music. We argue that these examples reveal transmediation acting as a process of ‘emptying’, allowing the music to carry its nostalgic cargo of affect into new relationships and contexts. This study’s theoretical combination of transmediation with Bainbridge’s object networks of social practice frame challenges normative definitions of nostalgia. The phenomenon of ‘emptying’ we identify reveals a function of popular culture nostalgia that differs from the dominant understanding as a triggering of generalized emotional longing for (or the desire to return to) the past. Instead, this article uncovers a nostalgia that is defined by personal and communal creative engagement and highlights the active and social nature of transmediated popular culture nostalgia.
