Songfacts®:

• This indie-rock-infused track by the Scandinavian dance music trio Swedish House Mafia was premiered on BBC Radio 1 on April 22, 2011 by DJ Pete Tong and released on May 13, 2011 as a digital download.
• The song features the vocals of the trio's fellow Swede John Martin, whom the threesome first came across the previous winter.
• 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."
• Artist Direct asked Axwell if they set out to do something with this song that the trio hadn't tried before? He replied: "We wanted to combine a lot of vocals and piano. We actually aimed to get them to work together in a house track. It's kind of hard to make a song bangin' with a lot of vocals and musical parts, but that was what we set out to do."
