It was released on June 2, 2017,[10] as the third single from their ninth studio album titled Feed the Machine.

[11][12] While giving interviews promoting their previous single "Song on Fire" to pop music radio stations throughout May 2017,[13] the band stated their next single will be much heavier as the new album Feed the Machine represents a return to a heavier, more aggressive sound compared to the band's traditional contemporary and mainstream sound.

[14] On June 2, 2017, "Must Be Nice" was announced to be the next single,[15] making it available via the band's official YouTube channel the same day as well as the digital libraries of those who had already pre-ordered Feed the Machine,[16] and revealed it will be sent to rock radio stations on June 6, 2017 as the official third single from the new album.

[17][18] "Must Be Nice" is an upbeat, hard rock song that blends gritty guitar riffs with playful, tongue-in-cheek lyrics.

Written entirely by lead siger Chad Kroeger, it uses nursery rhyme references—like "Jack and Jill" and "Humpty Dumpty"—to craft a sarcastic narrative about carefree or reckless behavior.
