[Tupelo]

” Why is it so groundbreaking?”

Simple answer is, it pushes the right buttons at the right time. Add another song from the early 1980s and you have a tandem that pushes the right buttons at the right time.
A Countryboy Can Survive - Hank Williams Jr
Rich Men North of Richmand - Oliver Anthony
In my opinion, these two songs should be played back to back.
