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: I bought this CD originally when I was in junior high, to accompany me while I practiced my saxophone (I preferred to practice to Beach Boys music over the school fight song). Anyway, it's also good for karaoke. However, be careful listening to the previous reviewer, who either can't count or has a different CD. There are 15 tracks on the CD, which last I checked is *not* over 20.
A:
Positive
