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: The player is awful if you are using it to listen to lectures; it only recognizes 25 minutes of an mp3. Plus, the fast forward function is EXTREMELY slow (to fast forward 10 mins would take about 3-4 minutes of holding down the button).Otherwise, it plays music fine, though the software on the mp3 player is no where near as nice as what you get with ipods (e.g. if you pull the headphones out of the jack it will pause the file, or it will remember the exact location in a file where you last left off instead of restarting a file if you turn the player off), but on the flip side it is also significantly cheaper.Overall, you get what you pay for.
Solution: Negative
