Being an MP3 and playlist-obsessive person, I gave this book a perusal at the bookstore. There wasn't a whole lot of thought put into many of these lists. Just because a batch of songs has the word "martini" in the title, for example, doesn't make them hold together as a playlist. When you're thinking about making a playlist for the open road, the songs you pick don't need to necessarily describe the road, but should make you feel alive and free. One of the downsides to itunes is that anyone can drag and drop songs and think they've made a worthy playlist. Real playlist making takes eons of internal debate (like John Cusack's character in "High Fidelity"). There is an art to making mixes that this book generally misses out on.
