There's a specific 4 note background electric strings riff in the Hamilton song "Right Hand Man" that starts up right after the "Boom" section (at around 2:20 and continues in variation through 2:45) that's maddeningly familiar! Where might I have heard it before?
I'm certain it (or something VERY similar) is in a hip hop song I've heard before but I've been listening to all my old favorites but no luck!
