As with This Is Hardcore, there will factually be plenty of mixes and alternate versions of songs. Pretty sure I saw a photo of a tape that had Mix 6 on say TV Movie. You also have "monitor mix" versions of songs too. It's just how rough do you go ?
Monitor mixes are rarely interesting. It's rough but its still the version that's on the record, most of the time, before mastering. I'd buy a reissue with a real remix, with new bits or a better audio because DC needs it.
