Listening to Amy Winehouse’s 2006 hit single “Rehab” while she was alive and publicly struggling with addiction was difficult enough. The surface delights of that song—its retro-style girl-group melody, its tight horn arrangement, Winehouse’s trademark bluesy growl—contrasted so starkly with the harrowing lyrics: “I ain’t got the time/ And my daddy thinks I’m fine/ He’s tried to make me go to rehab, but I won’t go, go, go.” A completely unfictionalized account of her then-recent experience with her bullying manager-father and a half-hearted and short-lived visit to an addiction and recovery facility, "Rehab" was a cry for help with a toe-tapping rhythm, a suicide note you could dance to.
