 "Reason" is a piano-led pop ballad with soft string arrangements and lyrics that talk about reminiscing past memories with a loved one.One of the slower songs on the album, its original version, entitled "That's the Reason", served as the closing track on both the original version of "Elle'ments" as well as its Special Winter deluxe edition.An updated version of the song, featuring new vocals, new instrumentation and slightly different lyrics was recorded following the band's announcement of their temporary disbandment in September 2003.
