I never knew much about Amy Winehouse. I liked her song Rehab because it was fun to sing, and yes, I did try to mimic her voice in a kind of caricatural way, because I like doing this when singers have a distinctive sound. (My favorites are Jon Bon Jovi, Brandon Flowers, and Cher.) And she was indeed unique. She had a style that was her own. She had problems. She was a rock chick. She was cool because she was different.
