I'll admit that I didn't "get" Dolly Parton for most of my life - not in the sense that I didn't like her, but in the sense that I just didn't understand why she or her music were such a big deal. Why she meant so much not just to the people right around her but people of all kinds, all over the world.
But this podcast miniseries did it for me: https://www.wnycstudios.org/podcasts/dolly-partons-america
I get it now.
