Change Music?

I’ve played Zeta before and I’m not a fan of hearing music from a previous game so I’m just wondering if anyone knows how to change the files to change the music ingame

It’s in the “Audio” folder.

I did and changed the new soundtrack I wanted’s name to what the replaced track is but when I play the music doesn’t change

Play the music and see which one is?
Then replace it with the same name in that folder?
