This chapter explores perhaps the furthest reaches of the two musical universes encountered in the book, taking as its subject the various practices and products of Harry Potter and Lord of the Rings fans and the ways in which they seek to extend or occupy the fantasy worlds themselves, either musically or sonically. This includes but is not limited to fan films and fan musics, looking firstly at composers of several fan films and their extension of existing musical vocabularies while walking the line of copyright infringement, before delving into the worlds of filk, wizard rock, ASMR and other corners of the Internet to examine the ownership taken by fans of these musical worlds and their reception among fan communities. The chapter also looks at soundtrack consumption and ownership as expressions of fandom, and the listening practices of fans and non-fans alike, including the use of film soundtracks to replace music of other games, or the consumption of film music while working or studying.
