"Destiny" is a song by English downtempo music duo Zero 7, written and produced by Zero 7 members Henry Binns and Sam Hardaker. After writing the music, the team recruited British singer-songwriter Sophie Barker, who provided additional writing. Zero 7 then met Australian singer Sia, whose manager recommended her to the duo, and she became the track's fourth writer. The song, a downtempo ballad, is about two separated romantics who wish to be with each other again, with one of the partners so desperate to interact with the other that she resorts to watching pornography in a hotel room. Sia and Barker contribute to the vocal performances, with Sia singing the verses and choruses while Barker duets with Sia during the choruses. The song was included on Zero 7's debut studio album, Simple Thi
