Our culture no longer bothers to use words like appropriation or borrowing to describe those very activities. Today's audience isn't listening at all - it's participating. Indeed, audience is as antique a term as record, the one archaically passive, the other archaically physical. The record, not the remix, is the anomaly today. The remix is the very nature of the digital.Link (Thanks, Michelle!)
Today, an endless, recombinant, and fundamentally social process generates countless hours of creative product (another antique term?). To say that this poses a threat to the record industry is simply comic. The record industry, though it may not know it yet, has gone the way of the record. Instead, the recombinant (the bootleg, the remix, the mash-up) has become the characteristic pivot at the turn of our two centuries.
We live at a peculiar juncture, one in which the record (an object) and the recombinant (a process) still, however briefly, coexist. But there seems little doubt as to the direction things are going. The recombinant is manifest in forms as diverse as Alan Moore's graphic novel The League of Extraordinary Gentlemen, machinima generated with game engines (Quake, Doom, Halo), the whole metastasized library of Dean Scream remixes, genre-warping fan fiction from the universes of Star Trek or Buffy or (more satisfying by far) both at once, the JarJar-less Phantom Edit (sound of an audience voting with its fingers), brand-hybrid athletic shoes, gleefully transgressive logo jumping, and products like Kubrick figures, those Japanese collectibles that slyly masquerade as soulless corporate units yet are rescued from anonymity by the application of a thoughtfully aggressive "custom" paint job.
