Book is over 600 pages and the print is so small it was difficult for me to try to read so I returned it. Perhaps if it ever comes out on Kindle I would try again.

This CD is great for some people, but I think a lot of other people are buying it who maybe shouldn't.For the Nirvana fanatic with money, get the full boxed set, you will probably find the DVD and the book to be worth the extra money, even if you don't listen to the added tracks.If you aren't a fanatic, stick with the albums. You will not like the low sound quality of the recordings.Now, for the Nirvana fanatic who's a bit short on cash, but absolutely has to have "Do Re Mi" as part of his collection, that's who this is for. "Do Re Mi" is an excellent track, one of Nirvana's best...so if you are a serious Nirvana fan, you DO need to have that one.

Ex Output:
Positive

I am a Senior at Linville High School. I recently read Hardy's Tess of the d'Urbervilles for my term paper. I chose it because a teacher told me it was very good. I was quite disappointed with the book in general. After reading the description on the back of the book, I inferred that Tess would be confronted with a problem, but being the "heroine" she was described as, she would overcome it victoriously. Unfortunately, I was completely wrong. Tess depressed and frustrated me extremely throughout the book. She cowarded down and let people run over her. The only thing that was good was the little surprises inserted every now and then. The whole book depressed me and I would rather not read another book of Hardy's again.
