I find it hard to draw exacting boundaries between rock, pop, folk and country. It's also pointless.
I always loved this "America Song" (admittedly, I thought it was a John Denver song, I wasn't aware about the argument who wrote it), it gives me goose bumps (in a good way) to this day, it's not chest-beatingly patriotic, but says something about the undisputable beauty of America as a geographic country.
BTW, in my ears this is more folk than country. Its vibe is even Paul Simonish to me.
