Yes, you saw that title right. For the theme song, since it was released on an album, there was a music video shot for it, but it was unreleased and was replaced with just clips of the show.
I honestly think the music video would just be the theme song, but with the normal text at the beginning saying something like: "The Nutshack Theme Song MYX TV *album*"
The guy who made the intro, "NUMP", I think his alias is, tweeted recently "Who wants to hear the full Nutshack theme?". This may have something to do with it, but I'm not sure. All I know is that the Siivagunner community is really excited for it (at least on r/giivasunner).
The transcript or the recording? I remember some people on r/giivasunner were talking about the full transcript on genius.com, but not all of that's filled out.
the video is lost of the full theme, the video (music video) was lost and replaced by clips from the show.
