[EX Q]: If I could give this half of a star I would. I am a big fan of Nirvana, but this was a total disappointment to me. The tracks sounded awful. I felt like I was ripped off in every sense of the way. I took it to a buy-trade-sell place and not even they would offer me anything for it, which shows you the poor quality of this album. A word of advice; DO NOT BUY THIS!!!!!
[EX A]: Negative

[EX Q]: I was sold this item only to learn, after opening the corresponding Web site necessary for eMarker function, that Sony was terminating the corresponding Web service in 45 days!!A great idea but no support.
[EX A]: Negative

[EX Q]: So, Amazon, you're back to selling whale meat, fois gras, and other gross foods? What gives? Is it because few American's eat it, or even know what it is? And, it's expensive which helps your bottom line. So, why not take stuff American's don't or are forbidden to eat (remember the ban on whale slaughter is now world wide and it makes your selling of it illlegal). People are becoming more informed on a daily basis, and finding this kind of stuff on Amazon is little less than appalling, much less, law disregarding.
[EX A]:
Negative
