"Millennium" is a song by the English singer Robbie Williams, released as the first single from his second studio album, I've Been Expecting You, on 7 September 1998.

[3] The whole writing process took about four hours, and Chambers described "Millennium" as "the simplest song Robbie and I have ever written - only two chords.

"[2][4] Once co-producer Steve Power heard the demo, which already had a sample of they found potential for a single given it showed a different sound from Williams' debut album Life thru a Lens.

"[2] Trident Studios in London was used for the majority of the recordings, including drums, bass and samples for the backing track, and the backing vocals, which included three female session singers and male vocals by Williams' guitarist Gary Nuttall.

Nick Ingman arranged the orchestra, which according to Power "was in the wrong key for 'Millennium', although we did want it to sound like the original sample in the choruses and we did refer to John Barry's original score for that", and conducted a 26-piece string section, plus harp and four French horns, at Angel Recording Studios in Islington to the programmed backing track, with a guide vocal over the top.

For speed, and to keep the creative flow going, we put them all down to separate tracks rather than spend time deciding which one we wanted loudest when recording.

The song became Williams' first number-one single in the United Kingdom, shipping over 400,000 copies and being certified platinum by the British Phonographic Industry (BPI).
