Castle On The Hill Ed Sheeran
Swedish House Mafia were last in the chart with their huge collaboration with Tinie Tempah, 'Miami 2 Ibiza' and now they're back.
2010 was an incredible year for the DJ trio, Axwell, Steve Angello and Sebastian Ingrosso sold a million singles and saw their upcoming UK Tour sell out in minutes.
The song features vocals from Swedish singer John Martin and the video features a lot of dogs! The video tells the story of a gang of vigilante pooches who are on a mission to save the world from crime.
Take a look at the preview for 'Save The World' and let us know what you think...
