Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: I have had this album on my 'must buy' cd list for some time and I finally got around to making the purchase in 2004. All I can say is that I should have purchased it earlier.A wash of alternative-rock-country-blues etched with dark and somber imagery. However it's not melancholic, just quietly introspective and laid-back.Works very well with a cup of coffee/tea, a newspaper and a lazy Sunday afternoon.
Solution:
Positive
