Thoughts on TAS Theme

What are your guy's thoughts on the theme for Star Trek: The Animated Series (1973)?

I feel like:

1. It almost sounds like the battle music for a Star Trek turn-based JRPG on the Nintendo DS.
2. I feel like PRO's theme gives very similar vibes to this one while having a distinct identity.
3. I almost feel like this theme is a weird in-between of the TOS theme and TNG-era theme (which makes perfect sense - I mean what else would be between the 60s and the 80s).
