The song was well received by contemporary music critics, who cited it the album's standout track and felt it was a breakaway from the Europop genre widely associated with the group; they also praised its production.

The single's accompanying music video was directed by Marcus Sternberg and filmed inside the New Trade Fair building in Leipzig in early October 2002.

The band performed the song on several occasions, including Top of the Pops, but while it was omitted from their jubilee album 20, "Let's Go to Bed" was part of Celebration Tour set list.
