Oh this one is going to bug me all week. I know the exact kind of song you mean, the storytelling kind where the last verse jumps forward in time, but the 911 part is not ringing a bell and I went through my playlists twice. Two things would narrow it down a lot. Was the phone call actual spoken audio in the recording, or sung like the rest? And since you caught it on Instagram, tap the audio name at the bottom of that reel if you can still find it. Half the time it links straight to the artist page. Post the name here and somebody will run it down.
