On 14 September 2015, Goulding teased her fans on Instagram by posting a 'mysterious, semi-topless gif with the date 17 September', announcing the song's release date.

On 6 August 2015, during iHeartMedia's annual music summit, it was revealed that Goulding's new single was called 'On My Mind' and was set to be released 'soon'. However, the release was postponed due to the commercial success of ' Love Me like You Do', released on 7 January 2015 as the second single of the soundtrack to the film Fifty Shades of Grey. Originally, 'On My Mind' was planned to be released in the first quarter of 2015, with British radio network Capital FM announcing that Goulding claimed that hopefully the single was set to be released around March 2015.

Its Western-themed music video, directed by Emil Nava, was inspired by the 1991 film Thelma & Louise and shows Goulding in a revenge story in Las Vegas. In the United States, it reached number 13 on the Billboard Hot 100. Commercially, 'On My Mind' became another top-ten entry for Goulding in the United Kingdom, as well as in Australia and other five territories, while reaching the top 20 in other seven countries. Multiple critics found it similar to the Police's 1979 song ' Message in a Bottle'. 'On My Mind' received mostly positive reviews from music critics, who praised it for being a radio-friendly song, as well as Goulding's vocals. Though firmly denied by Goulding, many critics considered it an answer song to Ed Sheeran's ' Don't'. Lyrically, 'On My Mind' talks about a one-night stand with someone the protagonist should not be with, prompting a dichotomy between heart and head. Written by Goulding, Max Martin, Savan Kotecha and Ilya Salmanzadeh, 'On My Mind' is an electropop and R&B song whose instrumentation consists of scratchy guitars, trap drums, slapped beats and sharp, syncopated electronica. It was released as the lead single from Delirium on 17 September 2015 by Polydor Records. ' On My Mind' is a song by English singer Ellie Goulding from her third studio album, Delirium (2015).
