"Spice Up Your Life" is a dance-pop song with influences of Latin rhythms such as salsa and samba. The lyrics are inspired by Bollywood films and reflects the group desire to "write a song for the world". The music video, directed by Marcus Nispel, features the Spice Girls in a futuristic setting, inspired by the 1982 film Blade Runner, controlling every aspect of society in a dark futuristic cityscape. The group promoted the song heavily, performing it on many television programmes and award shows.
Despite the lukewarm reception from music critics, it was a commercial success. Released as the album's lead single in October 1997, it topped the UK Singles Chart on 19 October 1997 for one week, becoming the group's fifth consecutive chart-topper. This made the Spice Girls the first act to have its first five singles reach number one in the United Kingdom. It performed almost as well internationally, peaking inside the top five on the majority of the charts that it entered. In the United States, the song did not perform as well as their previous releases, peaking at number eighteen on the Billboard Hot 100.
