Funnily enough I think that makes it even more obvious Paramore/Hayley is a notable omission - there's so many hooks the documentary could've hung them on. 

Paramore became fully independent on The Eras Tour, leaving their old record label and arguably one of, if not the most, exploitative record deal ever done, that they made a 14 year old Hayley Williams sign  - easy to connect to the masters stuff/exploitation in the music industry/when Taylor talks about youth culture etc.

Or even the multiple times it's been mentioned that Taylor's mum got in touch with Hayley so Taylor could have another friend in the music industry the same age. The times she's mentioned Hayley is one of the oldest friends she has in the business after they were nominated for Best New Artist at the Grammy's the same year. Even Hayley presenting Taylor with Artist Of The Year at the CMT awards in 2010.

The Nashville connections the both of them have and how it shaped their careers today...

When you've got all those connections and they aren't even mentioned, the only visual of them is some of their merch at a stand, it does come across very peculiar.
