Swedish House Mafia were last in the chart with their huge collaboration with Tinie Tempah, 'Miami 2 Ibiza' and now they're back.

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.
