what's the chord on "supposed to be" in your new song, relative to the key that section's in (so like ii minor instead of G minor)
that's Gmaj7 over A. we were in the key of F before, and soon will be in D. this chord is the first sign that we're breaking out of the key. technically this chord fits into the key of D, but that hasn't been revealed yet at that moment, so it doesn't quite count yet as the key of D. it's in limbo at that point
