amy winehouse may be not a very good role model to the community.she's problems with drug and alcohol abuse, as well as self-destructive behaviour, were regular tabloid news from 2007 until her death. In various interviews, she admitted to having problems with self-harm, depression and eating disorders.but no one can deny that she is one of the great singer ever,like it or not ,she's unique,she's ROCK and she's a LEGEND! really great voice.
