Over the course of the '90s, Shania Twain took country music deeper and deeper into pop territory. This playlist collects the earlier artists who made that move possible. First and foremost, that means Dolly Parton, whose "Why'd You Come in Here Lookin' Like That?" is as explosive and sassy as Twain's own hits. Aretha Franklin's R&B classic "Respect", meanwhile, was a direct influence on Twain's feminist anthems.
