What's an OSV?
If you mean OST, then yes, add it if you can track down all the release information (Amazon is a good place to start, but I like to verify the results with independent sources when I can). I wouldn't add anything off OCRemix unless it was a documented original work.
OSV = Original Sound Version. Many early (pre-PSX) game soundtracks were labeled as OSV (e.g. Chrono Trigger OSV). For all intents and purposes though, an OSV is the same thing as an OST; it really just comes down to what the publisher called it.
Secondly, as I already mentioned, I know what tracks are on the OSV and that metadata can be carried over. It's the release as a whole I'm asking about, and by extension the tracks that are not on the OSV. The release info of the OSV it not really relevant to the tracks being pulled from the game itself -- in most cases the game came out before the soundtrack. If anything the game release date and info would take precedence (though, artists and composers would obviously be the same as the OSV).
Lastly, what do you mean by "documented original work"? The chiptunes are ripped from the game files. They aren't original work at all. I only mentioned the OCRemix copies of the chiptunes because Voiceinsideyou used it as an example.
