"Invisible" is a song by Irish boy band D-Side, released as the third single (second in the United Kingdom) from their first studio album, Stronger Together (2003). The song was written and produced by Desmond Child, Andreas Carlsson, and Chris Braide. Released on 14 July 2003, the song became a top-10 hit in Ireland and the United Kingdom, peaking at number five in the former country and number seven in the latter. The same year, American Idol second two runner-up Clay Aiken covered the song and reached number 37 on the US Billboard Hot 100 with his rendition. The song has been frequently targeted by music critics for its unsettling lyrical content, with several calling the track a "stalkers' anthem". Release and reception D-Side's version of "Invisible" was released on 14 July 2003. Can't Stop the Pop called it a "meticulously crafted" track, praising its composition, the band's vocals, and its airplay appeal, but criticised the lyrical content for being too "creepy", noting that the chorus has aged poorly. Commercially, "Invisible" became the group's third consecutive top-10 hit in their home country, debuting and peaking at number five on the Irish Singles Chart on 17 July 2003. At the end of 2003, the song was placed at number 73 on Ireland's year-end chart. On 20 July, the single appeared at number seven on the UK Singles Chart, becoming D-Side's highest-charting single in the UK and staying in the top 100 for six weeks.
