For those of you who like to be really analytical with your music:

A friend of mine sent me this link to a site that provides in-depth analysis of virtually every Beatles song. It is written by American musicologist Alan Pollack. He makes only passing reference to lyrical content, as it is primarily a musical analysis. I've only read a few of them, but what becomes clear very quickly is that even the simple Beatles songs are full of little twists and changes that make them interesting. I've often wondered whether they wrote that way intentionally, or whether they just wrote what felt right to them, unaware of the underlying musical complexity that they were creating.
