Amy Winehouse’s 'Rehab' was born from a casual conversation between Winehouse and producer Mark Ronson while they were walking down a street in New York. Winehouse mentioned that her father and management had tried to make her go to rehab, and she jokingly sang the line 'No, no, no.' Ronson immediately realized the hook's potential and convinced her to turn it into a song. Inspired by 1960s girl groups like The Ronettes and the soul sound of Motown, the track used live brass and vintage recording techniques. 'Rehab' became a top 10 hit in both the UK and the US and won three Grammy Awards, including Record of the Year and Song of the Year. Its success sparked a global 'neo-soul' revival, clearing the path for other artists like Adele and Duffy. Despite the song's catchy melody, its lyrics remain a poignant and tragic reflection of Winehouse's real-life struggles with addiction.
