[9] May It Never Falter showcases Glaive's sound evolving from hyperpop to noise pop and electronic with elements of emo, according to Vogue's Taylor Antrim.

The album's opening track, "For God and Country", starts with samples of a choir, builds through fluttering beats, and peaks in a purgative crescendo.

Antrim considered it an improvement over A Bit of a Mad One and deemed the songs "For God and Country", "Everydog Has Its Day" and "Nobody's Fault / Accept My Own" standout tracks.

[13] The same publication also included "For God and Country" in their list of the year's best songs; Antrim called it a "densely layered" and "angsty" track, and concluded by stating that it is "catchy and relentless".

[12] Tyler Damara Kelly from The Line of Best Fit said "Live & Direct" "mark[ed] the beginnings of a new chapter in Glaive's artistry",[11] while Clash's Robin Murray called it a "Welsh-born alt-pop banger".

[10] All tracks are written and produced by Ash Gutierrez (Glaive), Cole Carmody (Ralph Castelli), John Cunningham, and Jeff Hazin, except where noted.
