Gazmen, I believe there should be that version you were looking for somewhere.
I gave a quick look to the tracklist you found on tracklistcovers, and I believe it is a mixture of the OST album and the FYC disc.
Even mgm's share (
Thread 198340), though containing bootleg music, doesn't seem to be Complete at all. Just give a look to the cues names: many cues are just edits and OST stuff, and some cues are definitely missing: for example, I found an unreleased cue using a link from the JWfan site (look at mgm's thread, at post #59 there's the download link).
On the site Chronological Scores (
http://chrono-score.blogspot.it/2012/10/super-8.html), there's the FYC disc too, and some cues of it are those on that tracklistcovers site.
I believe we should be looking for that FYC disc to have a true Complete (or, most complete possible) Score of Super 8.
