[2] Bill Frost of Salt Lake City Weekly praised the album's combination of guitar, synth, piano, and vocals "sweet enough to make fillings ache in Albuquerque", likening it to music in the TV series The O.C.

[5] Weekes wrote the song with harmonies intended to be replicated by concert attendees, but found that the Brobecks' fanbase was too small to meet his vision.

[7] Glass' voice is edited to be deeper in tone, while the instrumental features more bells and a choir,[5] made up of a crowd from a concert at The Depot[10] that later closes the song.

[1] Due to a lack of agreements for royalty payment distribution, the album wasn't re-issued after release,[11] leading it to only be available in full on YouTube unofficially.

[11] On December 10, 2024, the label's Instagram page posted a video teasing an official re-release of Happiest Nuclear Winter with the date January 1, 2025.

[13] Alongside its release, an upcoming documentary film titled Not Dead Yet was announced, featuring interviews and archival footage of the Brobecks' first two albums.
