Stapleton's version is full acoustic, with all of the focus on his Grammy-winning vocals. The simple production allows the story to be the forefront, and that production choice echos the silence that he speaks about in the relationship, adding another level of emotion to the track. The rasp in his voice at the high notes in the chorus evoke pain and emotion in a way he never showcased on his debut record, Traveller, and it shakes you to the core. There's no mistaking: his version of this song is one of the best songs to come out of 2017 so far.
Womack's version is at a faster tempo, and includes more production than Stapleton's does. The fuller production, along with background vocals from no other than Stapleton himself has a different effect: it adds a little less sadness and a little more acceptance than the pure grieving that can be found on Stapleton's version.
But the most interesting difference between Stapleton & Womack's versions of this song is point of view. In country music, as Maren Morris recently brought attention ti in her article for Lenny Letter, women tend to be forced into two specific roles: a woman scorned or a woman falling into rom-com style love. But on this song, Womack is neither. Stapleton singing, "I won't love you either way" fits the outlaw, tough guy persona of many men in country music and music in general. But a woman saying that? That's new ground to cover, especially in country music.
The verdict? Both of the versions are worth a thorough listen.
