Plenty of hit songs share the same four chords. What makes yours different is the night you’re singing about.

The structure underneath most songs is common property and has been for a long time. Nobody is distinguished by their chord choices, which means the thing that cannot be copied is the particular stuff: the specific evening, the person, the detail that only happened to you. That is where a song stops being generic even on familiar ground. The frame is shared and the contents are not.

Stop hunting for a clever progression and write about one real night instead. Put in two details you would normally leave out for being too small. If it sounds like somebody else’s song, add more of what only you were there for.
