Numerous releases of the song exist,[4] published variously by Sony Japan, R&S and Epic, including a number of promos. The fullest version is the standard Sony release, whose track listing is noted below. Other versions include, variously, a radio edit, a remix by Howie B, "Limbo" (another track from their Out Loud album) and the standard version of "4 A Moment of Silence" in place of some or all of the tracks listed below. Despite the extended track list of the standard version, it is still classed as a maxi single[2][4] by retailers although a discography page on the band's official site refers to it as an "album".[5]
In the early 2000s, a version recorded from radio was available on many MP3 file sharing systems such as Napster. The song was mistakenly identified as a track called "Digital" by the American industrial rock band Nine Inch Nails from their album The Fragile.[6]
