Q: 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.
A:
Positive
