In the words of Shania Twain, most of them 'don't impress me much'. I don't dislike them, either. Merle Haggard, of course, is a favorite. One or two of them, I have no idea what they've sung, either, so I can't make a judgment. I like a lot of what Dolly Parton has done, but she has a habit of over doing it sometimes. Still, even ones I don't care for, I know they do a fantastic job on this album, because otherwise, Don wouldn't have let their songs make the cut.
