"Rehab" is a song written and recorded by English singer and songwriter Amy Winehouse, from her second and final studio album Back to Black (2006). Produced by Mark Ronson, the lyrics are autobiographical and address Winehouse's refusal to enter a rehabilitation clinic.
"Rehab" was released as the lead single from Back to Black in 2006, and it peaked at number 7 in the United Kingdom on its Singles Chart and number 9 in the United States on the Billboard Hot 100,becoming Winehouse's only top 10 hit in the US.
"Rehab" became an international critical and commercial success, and has been referred to as Winehouse's signature song. It won three Grammy Awards at the 50th ceremony, including Record of the Year, Song of the Year, and Best Female Pop Vocal Performance.
It also won an Ivor Novello Award for Best Contemporary Song. Winehouse's public battle with drug and alcohol addiction, and subsequent death, have contributed to the song's continuing popularity and appearance in the media.
