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 disc proves that there's much more to the Campbell/Webb association than the 4 or 5 hits from the late 60s we all know and love. 'The Moon's A Harsh Mistress', 'Highwayman', 'Lightning in a Bottle' and 'If These Walls Could Speak' are particularly fine Webb songs and they're given superb renditions by Campbell. The chemistry has always been right between these two and I hope it's not the last we hear of them together.
Solution:
Positive
