No matter which channel you tune your car radio to, you'd have to be pretty out of the loop to never have heard Patsy Cline crooning about feeling so lonely and so blue. No matter what you think of country music, these classics are a must. But you'll need to be a true fan of this genre to match all of the singers in this quiz. Think of Dolly Parton's "Jolene." Tapping the toe of your cowboy boot while running through these country and western artists is optional, but highly recommended.
