Country songwriting is all about stories, and Jenn Schott knows how to tell them. On Tim McGraw’s “7500 OBO”, she mixes enough car details for an entire Bruce Springsteen album with bittersweet memories. On Mickey Guyton’s “Better Than You Left Me”, Schott presents a woman devastated by heartache and a window into her recovery. And for Rascal Flatts’ “Feel It in the Morning”, she evokes the thrill of finding love in a rush and hoping it hangs on.
