Ever since Liz Hengber first made a splash in 1991 as the writer of Reba McEntire’s blockbuster four-hanky ballad “For My Broken Heart,” she’s had a gift for matching a heart-tugging tale with a melody that makes it stick in your ribs. It’s just as apparent in the hits she penned later, like Bucky Covington’s dare-you-not-to-cry dad tribute “A Father’s Love” or Andy Griggs’ ode to an endlessly surprising love, “She’s More.”
