Trent Reznor clearly is becoming a leader in the remixing movement amongst better known artists as he says on the page with remix packs: “…there is no agenda here other than for you to explore, experiment, and have fun with it. depending on how this goes we may construct a more formal community for remix postings and/or possibly some sort of “official” endorsement by means of an EP or something.”
Many finished remixes can be found here. >NINRemixes.com: The official list of remixes of Nine Inch Nails’ open source songs.”
While the remix packs are conveniently pre-packaged in formats suitable for several different types of software, there seem to be no generic WAV or MP3 packs available. That makes it a bit harder for some remixers.
