Definition: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: After all these reviews, it is difficult to not feel like I would be doing an injustice ... yet, I think that those who claim to like Lhasa would much prefer the originality and talent of Chavela Vargas. Indeed, Lhasa's raspy voice is deeply influenced by the cigarrette-smoking Vargas. What is called haunting voice, or passion, by other reviewers, is a mode of interpretation that Lhasa administers indiscriminately to every song in her repertoire, especially when the CD includes merry Chrismas songs.
Output:
Negative
