I've been listening to a lot of this sort of thing lately: library music, hauntology, whatever genre name you want to hang on it. For those of us "of a certain age" it's the sound of old instructional films, elementary school filmstrips, etc. I suppose it's a sort of nostalgia, but it's looking back at a time that never was; a Gernsback continuum of shiny jumpsuits and jetpacks.
I owe a longer post about this sort of thing, honestly, but for now I'll leave you with a simple video.
Conversation enriches the understanding, but solitude is the school of genius.
