Have you searched with for instance EasyFind for file or folder names from the companies that made up CD Spin Doctor? Below is a sorta listing found in Spin Doctor's Manual.
BTW I also used this one a long time ago and since its demise switched to Amadeus Pro for doing the same thing. So I tried opening some files made with Spin Doctor in Amadeus. They do open (of course), however the track names window stays blank. Bummer for me too.
Here's some legal text with names to search for like Sonic or Algorithmix. Best of luck!
