Country music is insanely, hugely, ridiculously, really and truly popular. But, as we've been told repeatedly by those in and behind and affiliated with "Nashville," it isn't necessary to know and love country music to know and love this show. Yes, "Nashville" does center itself on country music and fictional stars in that arena both old and young, but that isn't the only thing it has going for it. The show will go beyond just the professional lives of the Nashville stars and give us some off-stage what-not too and that, dear readers, is universal. Connie Britton and Hayden Panettiere lead the cast.
