One viewpoint that may help with the intuition is that the Radon-Nikodym derivative is ... well, in most cases, it's a derivative. You know---derivative, like you first learned in kindergarten (or maybe freshman calculus). It's not just an analogy, it's a real genuine limit of a familiar sort.
Chapter Eight in our text Real Analysis (Bruckner$^2$*Thomson) develops these ideas if you care to look. You can download a PDF from here.
