In spite of the amusing typo in the title (Best fo), this is a high quality, inexpensive songbook. It has most or all of Tom's greatest songs -- which means some of the best music ever written. I'm still just beginning to work my way through it. Some of the songs are quite challenging. I've been working for weeks on Aguas de Marco (The Waters of March), one of my favorite Jobim songs. It is a lot of work, but I love having a good version of that song to learn from. It is worth the price for that song alone.
Haven't tried most of the rest of the songs because I'm so enamored with Aguas de Marco, but I did look at Girl from Impanema. That one had chords that were harder than a version I've used. Maybe it is more authentic, but I like the version I already know better.
I can't comment on the rest of the songbook yet. I will say that I am extremely happy with the little bit that I have looked at. And it was cheap!
