"Rehab" is a song by English singer-songwriter Amy Winehouse. It was released on 23 October 2006 as the first single from her second studio album Back to Black. It was written by Winehouse and produced by Mark Ronson. The lyrics are autobiographical, and talk about Winehouse's refusal to enter a rehabilitation clinic. It peaked at number 7 in the United Kingdom on the UK Singles Chart and number 9 in the United States on the Billboard Hot 100. It has since become a critical and commercial success internationally, and has been referred to as Amy Winehouse's "signature song". It won three Grammy Awards in 2008, including Record of the Year, Song of the Year, and Best Female Pop Vocal Performance, and was nominated for two more Grammy Awards. It also won a Ivor Novello Award for Best Contemporary Song. Winehouse's subsequent public battle with drug and alcohol addiction has resulted in some of the song's popularity and appearance in the media. The song has been covered by a list of artists. Two remixes featuring American rappers Jay-Z and Pharoahe Monch were released in 2008. A further remix by the electronic band Hot Chip was released in the United Kingdom.
