As the singer for Old Dominion, Matt Ramsey's had his share of hits, but he's also penned plenty of big tunes for other country artists. It's Ramsey's combination of unguarded emotion, attention to detail, and sly but insistent hooks that make his handiwork instantly identifiable no matter who's singing: Songs like Sam Hunt's R&B-inflected "Make You Miss Me" and Dierks Bentley's sweetly surging "Say You Do" are part of his considerable repertoire.
