Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: Eddie Palmieri, like most early-1970s jazz players, must have known popular music had taken over the world and caught the bug.Whether he wanted to make money or just expand his horizons, it really doesn't matter.He formed this band, Harlem River Drive, in 1970, and made one hell of an album. Truth be told, this project does not have much to do with the Latin Jazz Eddie is known for. Harlem River Drive is an out and out soul funk album: wha whas, grooving percussion, all the ingredients you would expect from a crack unit during the era.And more: with a baritone sax--an extremely underused instrument in all genres--in front, this album has a uniquely jazzy flavor, even though the beats could be off a Santana or War or Mandrel album.As funk, it works full bore, but the novel textures here make an already fantastic funk project so much more.
Solution:
Positive
