Filmation Soundtrack Recordings?

I showed my kids an episode of the old Filmation Batman TV show this week, and the music was great, and when searching for it, I found this super-depressing online post: https://www.filmscoremonthly.com/board/posts.cfm?threadID=40108&archive=1

TLDR; Hallmark has destroyed all the original elements of the old Filmation animated series. Why anyone does this kind of "let’s trash the archives!" nonsense in the era of infinite cloud storage is beyond me, and infuriating. Especially with a property as popular as, say, Star Trek.

Was there ever any of this music released previously? Or is it lost to time forever?

And if anyone here has any, could I get a copy?

You are not the only one who are looking for music from filmation series and others like ziv international. Its really unbelievable and hardly depressing. I dont understand either how this enterprises, destroy their material as they dont have any value for any one. And I dont know if exist a previous release of those musics. Really sad 🙁
