This book is really useful for people who love music. I don't mean in a music snob way but for those who are geninuely looking for new bands/artists to explore. It's set up like dictionary and each entry discusses an artist and then tells you what other artists you also might enjoy. What's great about this book is it goes beyond the obvious connections (i.e. if you like bowie you'll like roxy music, which is only true if you like specific eras of both artists. I wouldn't make that leap if I was only into Blue Eyed Soul era Bowie.) in order to help reframe groups you've already heard of but have not been compelled to check out.
