Thanks again John.

This description turned out 3 times longer than I had in mind.
I hope any of it is useful to you.

My personal SUNO method to date involves;

I'm not having to do too many iterations. Maybe 15-20.
I've got some prompts that deliver reasonably well for the lyrics that I write and "attitude" that I'm looking for.

For me, one of the nice things about working with such powerful co-writer is that I can focus exclusively on the lyrics.
I Try to stay in touch with the rhythm of the lyrics in my head. If they recite well, SUNO usually handles them well.
They don't have to be meter perfect, because SUNO will stretch and crowd words here and there to keep them on the beat.
That will usually add some character to the song. Particularly the stretching.

Once I get the first draft of the lyrics written and the syllables are rolling along in my head reasonably well, I upload them.
Sometimes I will really like the tone of the 1st iteration, but there will always be areas in the song that aren't working.
Then I will go back into the lyrics and start adjusting for timing, testing with iterations as I make changes.
Usually, I'm getting an acceptable overall sound on almost every iteration.
After 15-20 iterations, the timing kinks start ironing out and I get an optimal version.

Strange thing that keeps happening,
I'll get to what I think is an optimal version and decide, "I'm going with that."
It'll typically be about 8pm.
My wife will yell in, "I'm ready to watch some Netflix."
I'll say, "be right there, gimme a minute."
I'll click another 2 iterations, and almost unfailingly like one of them much better than what I have to that point.
So part of my method is too wait for her summons.

Your SUNO songs, particularly this last one, sound beautifully coupled to the music to my ear.

If you have time, please discuss your method.
