Zedd wrote this song with Matthew Koma, Skylar Grey, and the producer/DJ Porter Robinson. Koma can be heard on another Clarity
track, "Spectrum." Grey's composed parts of the T.I. song "Castle Walls
" and the Eminem/Rihanna collaboration "Love The Way You Lie
." Her talent for writing impassioned lyrics is apparent on this track, which finds Foxes singing about a doomed relationship that she can't leave behind.
