Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: Considering how much bad music is out there these days, this was nice to come across. Covers a wide range of topics and moods, musicianship is pretty good. I'd recommend it to just about anyone. My tastes are usually heavier and more progressive - Rush, Dream Theater, Iron Maiden, Queensryche. But I like this disc too.
Example Output: Positive

Example Input: Unfortunately, there is a major problem with the sound on this album and it's so bad that it makes this album unacceptable and a waste of your money. What a shame! Although I can clearly tell there was nothing wrong with Eddie Fisher's performance of this set of songs; the sound quality (and probably the mastering) of these tracks is every bit as poor as the other reviewer states that it is.Therefore, I would recommend one of two alternatives. Diehard Eddie Fisher fans will probably want both! First, there is the very good (even though it's currently out of print) CD entitled "Songs for Christmas" by Eddie Fisher which has two bonus tracks by Frankie Laine. Second, there is the CD that contains the music from three of Eddie's record albums entitled "Eddie Fisher Sings;" "I'm in the Mood for Love" and "Christmas with Eddie Fisher." In short, you'll be much better off with one or even both of these two other albums.
Example Output: Negative

Example Input: After reading Ms. Bluehorse's most recent book, Grandfather's Drum, I searched for other titles by her and found this one - The View From the Hill. While completely different from Grandfather's Drum, I feel that The View From the Hill is a mile stone in modern historical literature. Elizabeth writes so clearly, so expressively, so beautifully. She is a delight to read - even when her words are bringing tears to your eyes. Elizabeth, we need more or your books!
