On 11 March 2014, it was announced that Samantha Jade had written and recorded "Up!" as the official anthem of the Australian football team for the 2014 FIFA World Cup. "Up!" is an up-tempo, dance-pop song, co-written by Jade, Zac Poor and Mario Marchetti, with Marchetti serving as producer. Jade explained how the name of the song came about during writing sessions, saying: "When we were writing it we wanted something up-tempo and uplifting, so the word ‘up’ was the place to start." The track, which was recorded in Sydney, Australia in early 2014, drew inspiration from words in a book written by the players "documenting what it means to be a Socceroo." Jade described the recording as a "celebration-type record - it's about turning up the night and making the most out of things", feeling that it was a perfect song for the Socceroos.

"Up!" was released as a digital download and CD single on 11 April 2014. The physical single contained Jades cover of "Never Tear Us Apart" by INXS as a b-side. "Up!" debuted at number eighteen on the Australian ARIA Singles Chart on 27 April 2014, and was the highest debut of the week. This is Jade's third single release from her upcoming album to peak within the top twenty of that chart. The recording also appeared on the ARIA Australian Artist Singles Chart, peaking at number six. Mike Wass of Idolator called it "an absolute party-starter".
