"Restless" is the very first single of the Dutch rock band Within Temptation. It is taken as the first and only single from their debut album Enter. Although the song was released as a single, it never entered the charts, just like their following single, Our Farewell. There was no promotional video for the single.
The song re-appeared as a shortened remix on the band's The Dance (EP). The single version can also be found as a bonus track on the German (2003) and UK (2004) re-releases of the album Mother Earth .
