C.S. Lewis on re-reading

I like reading CS Lewis's writing.  When I learned of the book "On Repeat" by Margulis, I remembered the Lewis idea in "An Experiment in Criticism" that a literary person re-reads a book while the majority of readers feel that a book having been read is a book like "a burnt-out match, an old railway ticket, yesterday's news paper".  It strikes me as an interesting puzzle that Margulis describes a typical person, like me, listening to the same music repeatedly while rejecting the experience of re-reading a book - why does that seem like a natural choice?

Since much of higher education involves reading, I have a basic interest in how much and what parts of a book or a series of lessons people remember, adopt and put to use.  I noticed that I have watched the movie "The Russians Are Coming!" many times and Lynn has watched "Enchanted April" many times.  So movies go along with music, at least some, not with books.
