This question has been on my mind for years now, and I am hopeful that this community will help me in discovering this possible aesthetic.
I find difficulty in trying to identify my aesthetic because for me it seems that this certain aesthetic is primarily audio, specifically music.
This aesthetic spawns from my fascination with movie/TV soundtracks. I want to say it's an intersection of nostalgia/emotion/dreamcore, but I attempt looking through each aesthetic with no luck. I seem to be in a very niche corner in the aesthetic world(Another reason being that I am new to the aesthetic community, and I do not know a lot of the "vocabulary" to help myself). I've found it quite difficult to explain what category these kinds of songs fit into because it would most likely tie into the aesthetic itself, the one that I'm looking for. Songs I consider examples of this unknown aesthetic will be listed below.
Though for me this is primarily an "audio aesthetic", films and animations can compliment the aesthetic, the best example being pretty much any frame of a Studio Ghibli film. I appreciate anyone who takes the time to read/listen and I hope to get a positive response in the comments (wow this reads like I'm emailing my college professor)
Away - Meydan
First Step - Hans Zimmer
TVA Theme - Natalie Holt
Ad Astra Trailer Soundtrack
There are quite a few examples here, I wanted to make sure that you at least get a good understanding of what kind of music I am talking about, so that my aesthetic doesn't get assumed under "weirdcore" like it has in the past
