On 5 March 2015, Hozier played the song on The Tonight Show Starring Jimmy Fallon.

[1] "Work Song" was featured in the trailer for George Tillman Jr.'s 2015 film adaptation of The Longest Ride, a novel by Nicholas Sparks[citation needed] as well an episode of NBC's occult drama Constantine.

[5] "Work Song" has "nuances of soul" with a "strong melodic bass", composed of percussion, tambourines, guitar, and "murmurous" vocals, while the lyrics describe a love of "undying sweetness" and devotion.

[5][6][7] The song possesses gospel backing vocals and church-like hand-claps, with literary themes of love, sin, and religion returning to the record.

[13] Hozier shot the video the day after the Grammy Awards, and reportedly woke up with an "outrageous hangover" during the shoot.
