"Rehab" is a song by English singer and songwriter Amy Winehouse from her second and final studio album Back to Black (2006). Written by Winehouse and produced by Mark Ronson, the lyrics are autobiographical, and talk about Winehouse's refusal one time to enter a rehabilitation clinic. "Rehab" was released as the lead single from Back to Black on 23 October 2006, and peaked at number 7 in the United Kingdom on its Singles Chart and number 9 in the United States on the Billboard Hot 100,[1][2] her only top ten hit in the US.
"Rehab" has become a critical and commercial success internationally, and has been referred to as Winehouse's "signature song".[3][4] It won three Grammy Awards, including Record of the Year, Song of the Year, and Best Female Pop Vocal Performance.[5] It also won an Ivor Novello Award for Best Contemporary Song.[6] Winehouse's public battle with drug and alcohol addiction, and subsequent death, has resulted in some of the song's continuing popularity and appearance in the media.
In 2015, a documentary film about Winehouse was released, entitled as Amy and a performance on Jools Holland in 2006 of Rehab was featured in the film and on the original soundtrack. The song has been covered by a list of artists, from Seether to Jamaican Mento band The Jolly Boys, and from Hot Chip to Lea Salonga.
