I think it's better to have lines that DON'T rhyme than lines that do but they're only there because they rhyme. For instance, "Baby, when I met you, there was peace unknown / I set out to get you with a fine-tooth comb." What in tarnation does that mean?

I remember listening to an interview by Dick Biondi with Judy Collins. She talked about her lyrics and admitted she sometimes had to just be done even tho they weren't perfect. She noted that Leonard Cohen never would.

When I create a song, first I write down what I want to say. Then I start working it over to get it to rhyme and rhythm. If I can't then when I put it to music I put some stuff in there to draw attention away from the "terrible flaw".
