"Believe Again" is a New Age and electronica-influenced pop song written by Delta Goodrem, Brian McFadden, Stuart Crichton and Tommy Lee James produced by Stuart Crichton and Marius de Vries for Goodrem's third studio album Delta (2007).

The single, released in Australia on 8 December 2007,[1] features exclusive remixes and the unreleased B-side track, "Fortune and Love".

The song was written by Goodrem, McFadden, Stuart Crichton and Tommy Lee James just after Christmas in 2006.

[4] Goodrem also stated that for her the song means a positive, uplifting shift in her writing style.

I actually stopped writing songs after recovering from cancer because I just needed to feel free from such artistic environment."

The video, shot in a warehouse in Sydney, was filmed in the week ending 20 October by Paul J Varolo (Producer) and Michael Spiccia (Director), a friend of Goodrem.

When speaking exclusively about the video, Goodrem said: "There's flames and water – it's a real fantasy sequence, but it's quite dark.
