Ex Input:
The new sony is very poor quality . I bought this never having problems from Amazon.com before. They did not state that this was a Sony product and when I received it, all the CD had on it was a root kit virus. It would not even play in my CD player. When I tried to read the CD to copy and burn the "WAV" files to a new CD so I could just listen to the music, all there were on the CD was executables and no sound files. Sony is very poor quality now and I do not want to buy it again

Ex Output:
NEG

Ex Input:
In my humble opinion - . Guys...it's not that GOOD. I have the album on my computer, and I gave it a few listens, but...it has no substance. It's not interesting or anything new. It's catchy. And irritating, after more than a song or two. That's all ("Bandages" is enjoyable once in a while, I will concede). If you're looking for catchy and poppy (and there's nothing wrong with that), then buy it. If you want something new and original - don't. And if you want good indie dance/electronica-type music go for something like The Faint, The Bravery, or Le Tigre.

Ex Output:
NEG

Kingston Trio . Listening to this cd took me back to my growing-up years. I remembered all their songs I loved back then. It's a great homecoming
