Query: I love this book.

I love this book. When I was growing up, I used it in piano lessons and enjoyed many of the songs. it contains well-known songs as well as many which will become your favorites. It also has a variety of styles so everyone is happy with something. I like it because I am no virtuoso and the songs are difficult enough to be interesting (to play and listen to) and challenging, but not so difficult as to be unachievable. It has fallen to pieces, so I had to buy another one for my kids, who are just getting into this level.
