@stuartk I don't think there is any value in explaining my ignorant and half-informed definitions. By labored I meant more professional, with the goal of selling the product. Folk always felt to me like playing to themselves and their bubble and enjoying it. But of course your examples prove how I make no sense.
I studied music theory when I grew up but it was strictly for my country's musical background where there was folk, folk-dance, gipsy, beat, rock, and classical music. (Totally butchering it, my teacher would smash my head with a book)
And I totally understand if someone doesn't get Shania. I had a phase and it stuck with me.
