When it comes to art (audio or visual especially) iterating over a concept with some air of "generality" and "good enough" can have very interesting emerging properties. You get a "vibe" for what you want, but you might not have a perfectly clear idea of the entire composition until you actually see it in front of you, and then you iterate over that.

When I write a song I usually just noodle on my guitar with some pre-programmed drums in the background, I just play whatever comes to mind at the time, record it, then listen back to it, change a few things, add a few accents, decide to add another guitar line, maybe shift in fifths or sevenths to add more voices, add a few instruments that fade in and out like strings or brass, etc.

Some people might have more methodical approaches to art, and that's fine too, but in my case it's absolutely a 100% exploration effort about stuff that I don't even know I want until I see it in front of my eyes. These tools are amazing for this.

The benefit is that it's easier to request.
