You will be given a definition of a task first, then some input of the task.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Do not believe any of the so-called good reviews! This product is nonsense and simply DOES NOT WORK. I was able to install it rather easily. However, the flashy sophisticated website is NEVER updated! The play list are NEVER available! I am very dissappointed in Sony. Great concept, good looking product as usual fom Sony. Typical lack of performance. My experience is 180 degrees from the good reviews and I don't believe they are real or honest.
Output:
Negative
