Example Input: Where to start I have had this for 10 years and it is still ticking that alone is a tesament to how well the thing works. Over that ten years It has traveled with me to over a third of the world. This is to include half a tour in Iraq. It has been dropped and has been trough airport security more times than most people. Because of this I have never had a reason to buy an Ipod. And to be honest for music I would rather use this. Only reason that I own anything like an Ipod is that its my Iphone. So I think that the Xtra is by far the one of the best mp3 player made.
Example Output: Positive

Example Input: I've bought this book, underlined every hint of symbolism, found all evidence of romanticism, followed every quote involving thematic oppositions, and noted every example of Pearl's rebellious nature and social alienation, but I cannot find one positive aspect of this novel that makes any of my hard work feel rewarding. The only way this novel could give me a warm feeling is if I place it in a furnace.
Example Output: Negative

Example Input: Brilliant music made by old friends from the era when swing was still forming but at the same time the foundations of modern jazz were layed in Fletcher Henderson's orchestra ("Queer Notions" and some other songs).This is a really hot and swinging Henry "Red" Alllen's slightly dixielandish date, featuring Coleman Hawkins (tenor sax) J. C. Higginbotham (trombone), Buster Bailey (clarinet), Cozy Cole (dm), as well as some younger but still hot players.However, the leader is particularly expressive in the ballad "I Cover the Waterfront" - no wonder I found it cited as one of the classical Allen's performances. Late fifties were good not only for modern explorations: this hot hi fi session gives great joy to us fans of classical jazz who sometimes whish that the recording technology in the 20's and 30's was a bit more advanced...
Example Output:
Positive
