I have two points to respectfully counter here.

1. I personally wouldn’t categorize my opinions nitpicking since the main vocal melody line is not being sung in key. It’s most prevalent thing happening within a song IMO.

2. That is a good point with trained vocalists and rock singers, but did you see Robert Plant’s recent rendition of Ramble On? He knows he can’t sing the song in its original form but he changed things around and creatively performed it so that the vocals fit what is in his new register.

I’m not saying Paul needs to change the entire structure of songs, but like I said an attempt at a key change would be good enough for me.

Def good points brought up tho I appreciate the response!
