This is a wonderful book! You learn so much, not to mention its fun! My only critism is the font "A Bard's Book of Pagan Songs: Stories and Music from the Celtic World" was printed in, its kinda hard to read. Makes your eyes hurt after a bit. But, other than that, I had no problems whatsoever with this book. I reccommend it to all pagans and anyone who wants to learn more about Celtic paganism's history.
This is definitely a "topic specific" book, but if it's the topic you're looking for then you're in for a treat.
The author proceeds each musical score with a brief story about which the song is based. It's not cluttered with a lot of personal yarns. Very enjoyable. The CD is a great bonus!
