Dear studio engineers of classical music... or any studio engineers, really...
I don't EVER want to hear your HVAC system in a recording.
@Ricardus My personal gripe in that vein is that, as far as I can tell, there exists no recording of the version of the Star Trek: The Next Generation theme used in the end of Star Trek: Insurrection that isn't painfully dynamic range compressed.
Listen and cringe:

I don't expect it to make me tear up like the "welcome to Jurassic Park" moment in the Jurassic Park theme (https://www.youtube.com/watch?v=PJlmYh27MHg), but, as-is, it just leaves me feeling cheated.
@ssokolow My TNG disappointment is that I can't find a recording of the arrangement of Picard's song the way he and Nella Darren played it in the Jeffries tube. Just piano and Ressikan flute. There's all of these overdone orchestrations but that original is far and away the best. I'm actually friends with Michael Okuda the design artist who worked on the shows and the films, and I asked him to ask the music producer, and he doesn't think that version exists.
@Ricardus Ugh. That reminds me of another soundtrack travesty: The Ivory Tower from the Neverending Story soundtrack.
Luckily, in my case, a fan managed to cut together a voiceless film version of it.

It turns out some fandoms can be particularly dedicated on that front. For example, the Thomas the Tank Engine fans.
Some of them do things like https://www.youtube.com/watch?v=iafxUXvQ7L0 by splicing clips from different dubs and others even identify the synths used and make new masters.
@Ricardus Apparently what they put on the soundtrack is essentially a beta version of the piece that got used in the trailer but wasn't good enough for the movie.
