I think you have to tread carefully with "I don't get... a genre" type posts. Being keen on country music, it's an easy one for people to riducle & reduce to the same tired stereotypes, thus only serving to highlight their own ignorance. Ultimately genres are wide - take rock bands; I doubt many death metal fans like the 80s poodle perm stuff but in the eyes of my dear old Gran, it was all the same. Equally there's a huge difference between Johnny Cash & Taylor Swift.
Personally speaking, my Dad was a pro drummer in the 60s and Jazz is his main love. He's tried with me & the irony is all my musical tastes come from my Mum. About 10yrs ago I finally "got" Jimmy Smith's "The Cat" LP. I've also enjoyed a great night at The Jazz Cafe in New York. If you asked me if I liked Jazz, I'd probably lean towards no. I have the upmost respect for Jazz players though - remember the roots of the Motown house band? Also jazz creeps into all sorts of places - listen to early Alice Cooper. I'm sure the jazz purists would laugh but it's one genre nodding to another.
I always hated old English folk until I was invited to get up at a gig & play along. I could see the punk crossover that had eluded me in my youth. Great fun. Music is so vast, I never say never.
