Agreed, if you analyze it too much you can kill it, but still important to know the terrain if you want to do something worthwhile. Lazz and I got into it on Steve's recent thread (as you might have gathered from the comment above) wrt some of the terms you mention in the initial post. As you may or may not know I've come back to songwriting in the last few months after a brief fling with it some 10 years ago (been writing poetry mostly in the mean time, as well as doing software engineering to keep food in the dog's bowl) and have been studying, reading, learning, absorbing all I can fully intent on making a serious go of it (not for money!). I'm going to post my off-the-top-of my head summary wrt lyric and songwriting that I posted in response to a similar question on another forum:
--------------------------
Okay, here we go, I'm gonna try to regurgitate what I've been studying (mostly lyric writing) for the past few months
Start with an interesting and universal idea.
Start with a title then summarize in a sentence what that title means
Write in prose what you want to say in the first verse, same for verse 2 etc.
Write the Chorus - it should contain the title most likely as the first or last line
the chorus should summarize the message of the song, it should also (if possible) be tense and point of view neutral
so that the verses can "color" it.
Once you have the chorus written write the verses.
Once it's all written re-write it to make it better and then do that again a few times.
Know and follow the standard song forms (at least in the beginning) - AAA, VCVC, AABA etc. etc.
Use a rhyme scheme. If you use ABAB in Verse 1 use the same in Verse 2
Keep it simple but try not to use sing-song (simple) rhymes
The words should read like a normal sentence - do not invert word order for the sake of rhyme
The chorus words and music should be the same each time it is used.
As someone said above the title should be in the song. :Psmile.gif
Make sure the second verse builds on what is started in the first verse. (i.e. don't just say the same thing a different way, give us some new information.
Maintain a consistent tone through the song. If the first verse is angry, maintain it in the second verse.
The Chorus should contrast musically and lyrically from the verses.
A bridge is a one-time section that varies lyrically and musically from the other sections.
Leave room for the singer (and listener) to breath. (rests, pauses, silence is important)
The feeling of the music should match the feeling of the song (happy lyrics = happy music, sad lyrics = sad music) this is called prosody.
I'm sure I've forgotten a million things, but that's some good ones.

Hope this is useful.
