This song was originally introduced by the band as an untitled piece, but on Web sites it is often referred to as "Big Ideas (Don't Get Any)." Thom first heard this title from Matt Pinfield in a MTV interview for 120 Minutes. The title "Nude" is the title that appears on the band's set lists, though the song has never been referred to elsewhere by this name. The piece features both Thom and Jonny on keyboards, and it is as gorgeous and mysterious as both "Motion Picture Soundtrack" and "True Love Waits" as far as the unreleased material is concerned. Influenced by the notion that we live in a man's world, a place where men can get whatever they desire, the song also explores the guilt that men feel when they commit certain acts, like cheating on their partners.

On May 6, 2006, "Nude" was performed by Radiohead in Copenhagen at their first concert of the year. It is speculated that the band have recorded this song and it will be included in their next release.
