Ambivalence (Score 1)

I think charting the path to tonal ambivalence in pop music might be helpful!

V - I - V - I etc
to the
I - vi - IV - V
to the
I - iii - vi - ii - V - I
and the Most Ambivalent
bVI - bVII - I !
etc.

I'd like to see a visual representation of songs over time and their "distance" from the I - V polarity,
a.k.a. how "concealed" the swing of the I - V pendulum is,
a.k.a. if we are trying to eschew that duality in pop music.
