5 Seconds of Summer are also the first Australian act to achieve a number-one album with their debut album.
As of September 2015, the album has sold 734,000 copies in the United States. It also peaked at number one in 14 countries. It was certified platinum in four countries and gold in ten other countries.
On Metacritic, the album gained an average score of 65, based on 10 reviews, indicating "generally favorable reviews."
Billboard called it "a delightful debut from a group that cannot be easily pigeonholed, and is worth paying attention to."
Allmusic wrote: "Ultimately, 5 Seconds of Summer have crafted an album of songs that stick in your head like neon bubblegum on a hot summer sidewalk."
The Boston Globe wrote that "the lyrics leave no room for subtext--“Good girls,” goes the kickiest song’s thesis, “are bad girls that haven’t been caught”--and the gleaming instrumentation sounds untouched by human hands."
