What’s the song that kept you awake at 2am?

Not the one you played. The one you heard in your head when the station went quiet. That low hum between songs, like the world was holding its breath. I still remember the exact moment it happened—some old soul track, maybe 'Ain’t No Mountain High Enough,' but not the version you know. It was the crackle in the vinyl, the way the bass dropped just after midnight, and then… nothing. Just me, the dark, and that one line repeating like a ghost. What’s yours?
