Your list is interesting. When I saw this thread when it first started, I meant to post, but got busy and then forgot. The group on your list that I would have posted is Sweethearts of the Rodeo. I’m shocked that someone agreed with me. They were a victim of timing. When it came to awards, they were always up against the likes of The Judds and Brooks and Dunn.
