I've been reading a couple of books by George Pelecanos featuring Derek Strange and Terry Quinn. Love the books and his writing, but every once in a while I found myself hung up on the number of musical references. There must be dozens, if not a hundred or more. Every scene seems to have a song playing.... He is not the first author to load his writing with so many references. (Peter Robinson and Ian Rankin are two others that leap to mind). My question is, when does it become too much? Does a book need a soundtrack? And when the narrator is first person, does it detract from reality when he seems to recognize every song he hears, no matter what the genre?
