SHM member Axwell told the story of the song in an interview with Artist Direct
: "We wanted to make something that sums everything up after a two- or three-hour DJ set. It connects everybody to something pretty emotional and uplifting. We wanted our own end of the night track, and that was the idea behind 'Save the World.' We got this vocal from John Martin, and it was awesome to work with. It was a pleasure structuring the track with all of the parts. The challenge that we had was to make it energetic enough. Sometimes, when there are so many melodies, instruments, and vocals, it's hard to make the track uplifting. However, we managed to get the energy in there."
