A successful commercial career in country music requires, first and foremost, good songs, enough of a voice and range to put those songs over, and lastly, a personality and image that holds all of that together with a natural smoothness, all of which perfectly describes Kellie Pickler. No one is going to accuse her of being Patsy Cline, but Pickler's small-town girl-next-door image has served her well since she finished sixth on the fifth season of American Idol, and consequently found an audience, in 2005. This set collects the best and most successful tracks from her first three albums, including "Small Town Girl," "Best Days of Your Life," and "Tough," as well as her American Idol encore version of Cline's "Walking After Midnight," making it a nice introduction to the first phase of Pickler's professional singing career.
