I came across the phrase when I was checking up the lyrics of Every Teardrop Is A Waterfall by Coldplay:
I turn the music up, I got my records on
I shut the world outside until the lights come on
Maybe the streets alight, maybe the trees are gone
I feel my heart start beating to my favorite song
I was just curious whether it means the singer stayed reclusive all day until the night fell and streetlights were lit, or he stayed up all night until the sun rose...
