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: This cd is horrible!!! I thought that it might sound a little like there first, but it just sounded weird. It was so bad that when i put it in my cd player, i started bleeding from my ears. Skip this cd for gods sake and by something better like a rake or a loaf of bread.
Solution:
Negative
