During my season rewatch, the music leapt out at me in a way that I didn't notice the first time. Since then I've asked Alexa to play the Disco soundtrack a few times just to soak in it.
I am a big fan of new-era Battlestar Galactica, not least for its fantastic music by Bear McCreary, and I hear a lot of echos of that in Disco: lots of drums and "eastern" influences like reed-flute. And in the more "traditional" symphonic-sci-fi vein I hear an echo of the JJ-era Trek film scores by Michael Giacchino, which I also love.
Elsewhere in these forums, people have rated their favorite Trek show theme musicks. I'm a sucker for the traditional big-orchestra symphonic movie soundtrack style, so I would say: TNG, TOS, DIS, DS9, VOY, ENT.
As an aside, I have a personal obsession with the DS9 theme, and how it reflects the heights of cultural power that Star Trek held when the series came out. It's so gentle and contemplative, which is something a new show trying to prove its bona fides would never try to pull off. I once saw the DS9 theme performed live by an orchestra in Denver at an outdoor show that I just happened to be walking by; and it was remarkably powerful music! I was moved close to tears with the opening notes played by French horns. (And it's just funny that the main theme is played by tiny piccolo trumpets.) I'm a lifelong Trekkie and even I was surprised by my emotional response!
