Depends on the day. I grew up on 90s and 2000s country. There was some bluegrass in there but I moved on to alt/indie pop rock in highschool. Now I enjoy folk music, mostly the punk variety. AJJ is one of my favorite bands. I’ve never been into bluegrass to know the bands, except maybe Trampled by Turtles.
As others have said, genres are fluid and bands rarely stay in one category. Country music has had huge style shifts in the past 50 years. The same could be said of the various folk, anti-folk, and protest song movements.
I’ve discovered I enjoy the stripped down production of folk and acoustic country music. It makes the song seem more authentic to me. I also like the desperation and anti-establishment themes of punk music. So for me, folk punk hits the sweet spot of rebellion, sorrow, and simplicity.
