Sorry, I don't know these other books. I only know the one by Kazdin. And don't get me wrong, this guys knows research like it's nobody's business. It's just that the subject matter is dense and also he does not try very hard to make it more interesting. Not an awful book but leaves me wanting more.
Also, don't go by reviews only. I know grad students love to count things and measure things but that's an awfully small sample. In fact, sometimes the reviewers are friends of the author or people who just came from a book signing by the author, so if you ever come across two dozen five star ratings all made within two weeks, be suspicious. It could be legit...but be cautious. I speak from experience because I used to get Amazon to "sort" by "avg customer review" (silly me, thinking it was much more valid than sorting by "popularity") all the time. Some people are not even reviewing the books but the sellers, like if the book they got had some pages torn out or something.
The validity of reviews goes out the window once you get into books with political/religious content. I've seen people give scathing reviews to books they have not even read. The more extreme the language, the more likely they haven't read it. Good reviews usually make plenty of references to passages in the book, use quotes, use more neutral language. They don't say the author is antisemitic pig just because he criticizes Israel's foreign policy, or that the author is "evil" just because he respectfully disagrees with certain religious views. No, they actually read what's been written. In short, some reviewers have an agenda, and some are just not intelligent enough to be able to see the shades of gray and instead distort the author's perspective and what's worse, draw unwarranted conclusions about the author.
Do look at the reviews because they are valuable sometimes. If a lot of people complain about the background noise of an audiobook, make sure you listen to a sample before you buy. If they question the author's credentials, review them yourself. Sorry, I got off track. Hopefully somebody in the know will give us some stats book suggestions.
It must be something with music theory to torture folks. All my theory and sightsinging/ear training courses were at 8 AM as well.
