Hey OP - I feel your pain. I actually have
a lengthy write up/post (here) about how bad (most) of the tracks are (to my ears, at least).
To sum it up, as others have mentioned, a lot of the tracks just have a mindless 'cool jazz' (90's genre) vibe to them that just doesn't fit the setting and the stunning visuals. A layered and more mysterious sound track for evening/overnight with smoother and more relaxing but happy day tracks would have paired well with the visuals, and this is what I was expecting.
Aside from most of the tracks sounding the same, there is that one instrument that is constant throughout most hourly songs, and it just pierces through my eardrums. It's just annoying and can be heard (as a standout) even at the lowest volume setting. I can't think of the name of it, an 'electric something-achord'. Had that instrument been replaced with something more pleasant sounding, the songs would've been fine. Not great, but tolerable.
Then there is that old-timey trumpet that is used in the theme song as well as in a few hourly tracks... It reminds me of the sound effects that you'd expect to hear when old, sad clowns walk into a scene in an old movie. I just don't get it?!
I know not everyone is moved by music the way others are, but when you put hours and hours into gameplay, the music (which cannot be disabled) is a big part of the experience. I wish more evening tracks sounded like
5am, and more day tracks sounded like
12pm.
I don't know if they used a new music team for this release, or there wasn't enough time to perfect a better soundtrack. Just thinking back to 10pm and 11pm in WW and 11pm in NL (to name a few as most of NL tracks were magical), just as examples, wow, those were amazing tracks that really just set the mood. Those beautiful French accordion sounds, or whatever they are, are missed. They are a staple in AC, but they are only in one track in NH.
Comparing the soundtracks from WW and NL to NH, you just have to wonder what they were thinking...
