Example Input: As a musician and musicology student, I am very familar with both the "classical" world of music, and the popular world of music, and I have to say that perhaps string quartet versions of R.E.M. might be interesting, but you need a creative and enterprising quartet (such as Kronos Quartet, etc.) to do this. This CD is greatly disappointing because the transcriptions are simplistic and lacking imagination. String quartet recordings can be very exciting, but not here!
Example Output: Negative

Example Input: This game would be one of the best of all time games if it had a map editor/creator and you could make your own larger maps AND if the buildings didn't need repair every hour. At first when you build them its not too bad, but once you get about 200 people, fixing every building every hour is EXTREMELY tedious!I absolutely LOVE this game other than that.I get to open a nice vacation spot and people always come, even before you're ready to have them they come... complain and leave, but they keep coming anyway! They are pretty easy to please once you build up a few essential buildings like bars, toilets and water rides.I hope Eidos didn't forget about such a fun game with so much potential! I would really love to see an expansion pack with islands I could create and more efficient buildings that don't break down everyday!I love this game and will play it forever :)
Example Output: Positive

Example Input: I have been very unhappy with this product because it:1) makes a high pitched buzz2) intermittently stops providing enough power causing my computer to constantly switch back and forth between battery and wall power.3) the cord is difficult to wrapI'll be trying to return it through the warranty process, but I wish I had just coughed up the [lots of] extra money to buy an Apple one.

Negative
