While we're on the topic of song structure - can anyone have some books on the topic of pop songwriting harmony that they found useful (not that all the answers are in the books - but they're a great starting point for me).

In fact, sometimes just having a name for things can help the composition process - I saved jazzman dan's list for that very purpose.

Finally - as Pat mentioned - those songs with the exact same chords used in both verse and chorus - I'm always impressed when I learn that a song that has maintained my interest falls into that category - not so easy to write something so 'easy' and have people like it so much - IMHO.
