Safe In Sound

This samples an old Irish folk song sung by Mary O'Hara. It's the same sample that Passion Pit used for their song, "Sleepyhead." Sub Focus told MusicRadar.com: "I really love the sample and had a track that worked around it so well that I used it."

Sub Focus co-wrote a lot of the song with Seton Daunt, who is best known as lead guitarist for the British rock band Fiction Plane. That is why the intro is all live guitar.
