Unbroken is the third studio album by Irish boy bandD-Side. The album was released on 25 October 2006 in Japan, and later released via the iTunes Store worldwide on 3 March 2008.[2] The album peaked at number 58 on the Japanese album charts. Two singles were released from the album: the title track, "Unbroken", and "Let Me Be the One" (which serves as a promotional release only; no official music video was recorded for the song).
"No One" was an unreleased track written by Bryan Adams.[3] The album features writing contributions from a number of well-known songwriters, including two songs penned by Steve Mac and Wayne Hector ("Missing You" and "Then You Kissed Me"; the latter of which was an unreleased song by fellow boyband Westlife). The album's title track was also co-written by Phil Thornalley, famous for his work on Natalie Imbruglia's debut "Left of the Middle". The band co-wrote the mid-tempo ballad "Fly" with songwriter Kai McKenzie, who produced several tracks for the album. The original Japanese release includes four tracks omitted from the worldwide digital release, including the Mac-Hector "Then You Kissed Me".
