it’s has a bunch of subgenres, there’s stuff like Eccojams Vol. 1 and Floral Shoppe that combines a bunch of clips from 70’s to 90’s music, and in some cases commercials, some of it sounds like elevator music but other stuff sounds more like old TV and car radio that gives it that more nostalgic vibe
There’s other stuff that’s more synth like HOME - Resonance but that’s more synthwave than anything
