Any song on Wilder Mind that's upbeat is a surprise. In the case of "Ditmas," it's certainly a pleasant one. The song nearly lilts as it rushes through the story of yet another love that isn't working out, this time through the fault of a woman who accuses Mumford of having changed even while she leaves him behind for a "[a] life lived much too fast." The song is sad, but it's not mournful; Mumford argues deftly and powerfully-he won't let the blame for the end of this relationship fall on him.
