Yes there's hold music, and yes there's <pink> noise for falling asleep (has a falloff), but in either case I personally don't think it should be on Spotify/another generic music streaming service.

Put a different way, if I'm listening to music on random, and Led Zeppelin finishes, do I want there to be a chance of pink noise or elevator music playing after that song? Not really, but if "it's all on Spotify," then it could happen

Sure, but if Spotify gives you that after Led Zeppelin, then that sounds like a Spotify problem, not a problem that this music is on Spotify in the first place.
