Songs written by Lily Allen

"True Love" is a song written and recorded by American recording artist Pink from her sixth studio album, The Truth About Love (2012). It was written by Pink, Lily Allen (credited as her former marital name, Lily Rose Cooper) and Greg Kurstin, and features Allen.

"Who'd Have Known" is the fifth and final international single (fourth and final in the United Kingdom) by British recording artist Lily Allen from her second studio album, It's Not Me, It's You. Written by Allen and Greg Kurstin, while interpolating Take That's single "Shine", the song was released as the fifth and final single from the album on 30 November 2009 by Regal Recordings. Contemporary critics complimented the song and Allen's warm vocals, while the music video portrays her as a groupie of Elton John.

"Back to the Start" is a track on Lily Allen's second studio album It's Not Me, It's You. It was released as a promotional single from the album, and also as a 7" vinyl record with one of Allen's previously-released songs as a B-side, "Kabul Shit".

"Not Fair" is a song by British recording artist Lily Allen from her second studio album, It's Not Me, It's You. Written by Allen and produced by Greg Kurstin, the song was released as the second single from the album on 19 February 2009 by Regal Recordings. The song incorporates country music as the lyrics depict sexual frustration. Contemporary critics did not positively receive the song and its theme, some calling it a "pseudo country track" and considering it a strange musical composition. The single peaked in the top twenty of the charts of some European countries and Australia, while scoring Allen's second consecutive top-five hit on both the UK Singles Chart and the Dutch Top 40 (since in the latter "Fuck You" was a commercial success before "Not Fair").

"The Fear" is a song by British recording artist Lily Allen from her second studio album, It's Not Me, It's You (2009). Written by Allen and Greg Kurstin, the song was released as the lead single of the album. Initially, "Everyone's at It" was announced to be the first single from the album. However, it was ultimately decided on "The Fear" to be released on 26 January 2009 by Regal Recordings, while the demo (which was then titled "I Don't Know") leaked onto the Internet in April 2008. The song incorporates electropop music as the lyrics articulate problems with celebrity lifestyles and include metaphors for recognised tabloid national newspapers such as The Sun. "The Fear" also references, albeit indirectly, the Great Depression of the 1930s.

"Fuck You" is a song by English singer Lily Allen from her second album It's Not Me, It's You (2009). It is her third international single. The song became a quasi-gay anthem because of the song's lyrical message. The song was featured in the pilot of ABC's Suburgatory.

"22" is a song by British recording artist Lily Allen from her second studio album, It's Not Me, It's You. Written by Allen and Greg Kurstin, the song was released as the fourth international single of the album, but the third in the United Kingdom, after it was decided not to promote "Fuck You" there. It was released to the music market on 24 August 2009 by Regal Recordings, though a different version called "22 (Vingt Deux)" was released in France.

"Shame for You" is a song by British recording artist Lily Allen from her debut studio album, Alright, Still. Written by Allen and Blair MacKichan, while sampling Jackie Mittoo's "Loving You" melody, the song was released as the A-Side to her fourth single, "Alfie", exclusively in the United Kingdom on 5 March 2007, by Regal Recordings.

"Littlest Things" is a song by English singer Lily Allen from her debut studio album, Alright, Still (2006). Written by Allen and Mark Ronson, the song was released as the third single of the album on 11 December 2006 by Regal Recordings. It incorporates a piano sample from Pierre Bachelet and Hervé Roy's music from the softcore pornography film Emmanuelle, for which they were credited as co-writers, as the lyrics tackle the singer dealing with the departure of her boyfriend, while reminiscing about their time together. The song was created in a New York studio, after Allen had met Ronson, who was impressed by her previous work and offered her different samples.

"Alfie" is a song by British recording artist Lily Allen from her debut studio album, Alright, Still (2006). Written by Allen and Greg Kurstin, the song was released as the fourth and final single from the album, on 5 March 2007, by Regal Recordings. In the United Kingdom, it was marketed as a double A-side single, along with "Shame for You". While the melody incorporates a sample of Sandie Shaw's "Puppet on a String", the lyrics directly describe Allen's real life younger brother, actor Alfie Allen, criticising him for his lazy behaviour.
