This is worse than crap. Every song in unaccurate when compared to the other tab books (I have of the Official NIRVANA song books). Probable, the only thing correct is the lyrics, but thats not the reason to buy this.The guitar tab is horrible, and useless. Its uncorrect on the simpliest songs, such as "Come as you are" and "Sliver". Actually, "Sliver" is unbelievably wrong. The bass notes are written for like 3 beats, when the intro has more than 15.The pages, and print the book uses is cheap and disturbing when you try to play the uncorrect songs. Its hard to look at, because they tried to squeeze everything into a small space, so they cut down on the quality of print and it looks like the authors spent no time to correct their errors.So seriously, this is a REALLY BAD buy. If you really need a nirvana tab book, i would get the greatest hits tab, or individual cds (Nevermind and In Utero).
