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

Problem: I loved this video! Having bought multiple copies of the album, cassette, and finally CD (which doesn't wear out!), it should be obvious that I'm ecstatic about the music. Now, I've added this wonderful inside look to my collection. If you're a Fleetwood Mac "Rumours" fan, this is the best gift you could receive from someone! Every Fleetwood Mac fan will love this on their shelf to replay at will. Phenomenal!
Solution: Positive
