Imagine that pleasant middle-of-the-night state, encapsulated into a song.
David Cutter did exactly this with his utterly relaxing "Nightline" - dreamy synths with bumpy beats. And I'll leave you with the thoughts he shares:
You are sitting in your apartment, the air is still, there are no cars on the roads outside, the world seems asleep, but beneath that quiet exterior is a subtle sense of connection to other people experiencing the same thing in a distant place, you make a call to the nightline, there's no need for conversation, you both listen to the hiss and occasional crackle of the line, just two people silently keeping each other company.
It's always night somewhere, so sit back and enjoy this.
