Query: Not for youngsters

I just want to disagree with those reviewers who say that if you are over 40 this book is not for you. I am over 50, and I find the song selection of this book to be outstanding. I am sure my 21 year old son wouldn't identify with it, but I recognized almost all the song titles and found the variety to be outstanding!
