What's that joke about country music? That if you play it backwards, the singer gets his car back, he gets his wife back, and he gets his dog back? There's a particular narrative in country - men's
country, at least - that lends itself to formulaic and often-times jingoistic sentiments that have never really appealed all that much to She Said.*
Women, on the other hand, seem to write country music from a broader range of emotion and experience. With a genre as intensely emotional and sentimental as country often is, it makes perfect sense that women would excel at it.
