If you're the type to listen to all kinds of music, i will definitly recommend the EP "Philosophie du Soi" by PAON
The cover is absolutely ethereal and so is the music, it's giving the same vibes as Nier Automata, Ghost and the shell with a bit of Persona music
It's very hard to truly describe it but one of the ways to put it is that "the music sounds exactly like the cover art looks"
