Beyond her confessions of rebellion and rehab, Amy Winehouse was a master of intimacy, whether covering an R&B classic or collaborating with a hip-hop star. Her take on Quincy Jones' "It's My Party" drips with sass, and with Nas, she makes a potent, jazzy brew that goes down smooth ("Cherry Wine"). At her most devastatingly self-aware, the seductive "Amy Amy Amy" draws you in with every subtle turn of a syllable.
