Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example is below.
Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: Just to be clear: the album is uniformly quiet and just consists of electric guitar without lots of special effects except long sustain. The genius of the record is that MazzaCane can bring out so much with minute details -- muffled string noises, minute pitch changes, perfect arhythmic timing of notes. Don't mistake apparent simplicity for emptiness, as another reviewer did. One of the most moving records I've heard, with a rare, sad, clear quality. I'd recommend this as a first album by this artist (he calls it his best too).
A:
Positive
