I never sit down and write. I just sorta let things form in my brain.
I don't sit down to write a song; they just come to me from something that somebody says, or something in the news. The punchline comes to me, and I go over it in my head and get the song form. I hadn't been doing that a lot.
If it's worth remembering, I'll remember it. If something keeps coming back, if I keep thinking of that phrase, if I see manifestations of it at different times and different places, then I feel it's worth making a song out of.
You always want to write the perfect song. But no one will ever write the perfect song, I guess. I would just like to write on that has all the elements of what I'm tring to do. And I'm working on it. I'm always working on it.
I start out with words, with the idea, the line. Then after I get a line or two, I try to find what melodic line those lines would be suited to. As soon as I find the form I can finish the song in my head.
