Quick question, hoping someone here can shed some light on this:

I see stuff like this from time to time:

Mulan Soundtrack (Deluxe Edition by Jerry Goldsmith) | Download Soundtracks (http://download-soundtracks.com/movie_soundtracks/mulan-soundtrack-deluxe-edition-by-jerry-goldsmith/)

Yet I see no listing of this actually being available anywhere for sale. Does this mean this is likely some fan made thing, with lots of sound effects left in and stuff?

Here's another one, again, no place to buy this officially as I can tell:

Small Soldiers Soundtrack (Deluxe Edition by Jerry Goldsmith) | Download Soundtracks (http://download-soundtracks.com/movie_soundtracks/small-soldiers-soundtrack-deluxe-edition-by-jerry-goldsmith/)

I have nothing against fans who make their own scores using blu rays and what not, but I'm not a huge fan of them myself. I'm wondering if anyone can tell me if stuff like this is official or just something a fan put together.

Any thoughts on this would be greatly appreciated.

I'm not familiar with either of the links you listed, but it can just be edits of leaked recording sessions. Neither those edits or the sessions are officially available, but blessed be the people who leak the stuff that SHOULD be legally available in the first place.

Both of those scores are SonicAdventure's custom deluxe edition presentations.
They originated here, not that Download Soundtracks site.

For example, here's one of his threads:

Thread 188354

They are not made using sound mixes from Blu-rays.

Oh no, I was pretty sure that if those scores WERE custom, they were made by someone here.

I just wanted to see if they actually were customs or officially released and I guess now I know.

I wish they'd release this stuff officially, I'd gladly pay for it. Until then, thank you SonicAdventure for all your hard work.
