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

Example Input: I don't actually own this album, but I did buy Apple Venus, and I'll say this: I hope that this album has the charm that that album lacked. I've never been so disappointed with an XTC album. Why would one buy an album of the exact same songs, except in demo form? A shoddy attempt to extract money, it seems. Shame on you, XTC!
Example Output: Negative

Example Input: I recall this recording on LP in the early fifties. It conveys the humour and genius of Mozart with great singers although other than Steber they were not previously identified with WM.
Example Output: Positive

Example Input: If you search for Super Saver shipping this advertisement comes up, but this product is not shipped by Amazon is does not go out with the Super Saver shipping, and the cost of shipping is nearly 20% the cost of the pants.
Example Output:
Negative
