Who Is Your All Time Favorite Country Star?

I know this is a tough one, because there have been a lot of country music stars over the years. Can you pick just one artist you like more than any other? At first, I was the biggest Hank Williams Jr. fan on the planet, then I got to watching classic video's of Conway Twitty and how he put so much emotion in every thing he sang. So, I would have to say Conway Twitty for me! Now I want to know your favorite?
