"We Are Young" was released as the lead single from the album and bolstered the band to mainstream success with the aid of television and advertising.

Lead vocalist Nate Ruess, who had apprehensions about joining a major label in the past, recalled the switch being "very, very easy" for the group, stating that both parties approached it as if they "knew what [they] were getting into with each other.

Ruess was flattered that employed workers for the label would buy their own tickets to Fun shows and "talk about us with the passion you'd generally reserve for an artist you're working with."

[4] Ruess recalls that he was listening to "so much hip-hop" during the production that it became a big influence for him, specifically Kanye West's My Beautiful Dark Twisted Fantasy.

Dost noted that in recording, despite the composer's well-defined framework, the individuals' egos "pretty much disappear" and "everybody is happy to work towards the best possible song" cohesively together.

[11][12][13][14] Rolling Stone's Jody Rosen, called the album a mix of "close harmony chorales, showy key changes, a dash of Queen here, a dollop of Les Miz there".

[13][16] Tyler-Ameen considered the album "remarkable for its sheer optimism", despite the sad and mournful lyrics,[16] Rosen wrote that "Ruess' knack for the anthemic is matched by Gen-Y humor – emo self-deprecation that leavens the bombast".

Glee's cover of "We Are Young" was the show's highest selling debut single of their season and connected their listening audience to the band.

[6] Even after being benefited by the high-profile cover, "We Are Young" became the soundtrack to a Chevrolet spot that aired during Super Bowl XLVI, which brought Fun to a type of exposure that Billboard noted "few current bands receive.

As a thank-you to their fans for their support of the band, Fun streamed Some Nights in advance on their official website a week before the album's release.

[20] "All Alone" was performed on Alan Carr: Chatty Man on April 19, and was released as the fifth and final single from the album on May 13, 2013, in the United Kingdom.

[13] Sputnikmusic staff reviewer Adam Knott wrote, "The energy and personality which flood out of every melody give this album its own stamp of authority.

[38] The album's lead single "We Are Young", became the first multi-member band debut to top the Billboard Hot 100 since Nickelback's "How You Remind Me" in December 2001.
