Although, many recordings of film music have been released that are not included in this database (extensive as it is).

A number of official releases are missing, and only about 10% of all bootlegs are listed. SC is not the end-all-be-all of CD/CD-R listings.

Hello! I don't know about Flesh Gorgon, if you're looking for the Green Slime music I can help you out a little bit. As far as I know there is no complete Green Slime CD issued in Japan. However. on the "King of the Monsters" 10 CD box set, I can tell you that there a 4:05 suite of music from "Green Slime". This piece of music seems to be a re-recording of the music as this final disc in the set consists of re-recorded suites of music (Green Slime and Godzilla 1954) as well some music to some films that were current at box set's release (the new Godzilla vs the Thing, and Godzilla vs King Ghidora, the "mecha-ghidora" that is). I hope this helps!
