Nice choices. I wouldn't say I'm particularly a country fan, but there are some songs I like a lot. From your selection, Wagon Wheel and Where Were You were my favourites.

I always liked this one from Glen Campbell & Bobbie Gentry

And Keith Urban is a favourite (of course he is a kiwi...)

If you want to check out some recent stuff, the soundtrack from the TV series of Nashville is awesome. Just a smattering:
