Which side does the ear lean to?
Our reading: to us the song feels closer to the Ab major side because it both starts and finishes on Ab and Ab is heard 12 times against 8 for Fm. That is an interpretation, not a rule — hearing the same chords from F minor is just as valid and teaches you something different.
Show the degrees above the chords — relative to Ab or to Fm; comparing both readings is a practice of its own.
Every chord of the key, listed 1 to 7 separately for each key. Chords played in the song show how often they appear; chords from outside the scale sit next to their own degree.

The key pair is Ab major and its relative F minor (4 flats). 10 different chords appear 65 times in total; 8 of them sit naturally inside the shared scale. Bb7 acts as a secondary dominant, briefly pointing at another chord of the key.
The move to watch is Bbm7 → Eb7, heard 12 times. From the Ab side it reads ii7 → V7 (ii → V: the classic preparation of the dominant); from the Fm side it is iv7 → VII7. Knowing where these arrivals fall helps you feel the phrasing and anticipate the next chord.
Empty slices are chords the song doesn't use.
The opening Ab lays a solid floor for everything that follows. The chords that keep coming back are Eb7, Ab, Bbm7, Fm; read them as V7–I–ii7–vi in Ab or VII7–III–iv7–i in Fm. Bb7 adds a moment of surprise: secondary dominant V/V — leads to Eb. Keep an ear on Bbm7 → Eb7 (ii7 → V7 in Ab, iv7 → VII7 in Fm): ii → V — the classic preparation of the dominant. Ending on Ab, the song seals Ab as home.
