Back to Black (the song) is the best. “She” (if she is indeed a lady) has a fabulous voice. I really like the 60s type jazz drums sound. All of her songs are suspiciously familiar – like they have been out for years already. Maybe the songs have just picked up heavy influences from elsewhere.
Again, she has a great voice – her songs helped me get through my Uni exams and I can play her songs endlessly without getting bored of them!!
