Released as the title track and second single from her legendary, multi-platinum 2006 masterpiece Back to Black, Amy Winehouse’s signature song stands as one of the most haunting, emotionally devastating, and timeless achievements in modern popular music. Produced by Mark Ronson and recorded with the legendary Dap-Kings, the track merges the lush, tragic aesthetic of 1960s girl-group pop with raw, contemporary heartbreak, cementing Winehouse as a once-in-a-generation vocal and compositional genius.
