When I write a song I try to capture the first moments of it, as writing it, -- not practice it then "record". I always save the first pass(es).
What I then try to do, is then "practice" it to *keep* the first moments freshness in it.
Because, for me, if I then practiced it allot then "recorded" it, to then be itself, -- many more would sound alike than may already. I know I/we-all have a sound, but doesn't mean self-cloning, etc. (E.g., Led Zep wrote "when the levee breaks", once, never again.)
-- "Happy accidents", lost... with to much practice.
In all the folks I've known or "studied", observed, -- they create then record nearly immediately, (chop out songs from hours of tape/demo/jams (i.e. the Stones), then practice for "tightness" and other if even comes together; they don't write, play'em for a year then release them.
So, what? Good question
I don't see this discussed; actually, I don't think I ever observed it discussed. Maybe it doesn't need to be discussed , however, I like looking at the brutally obvious, not talked about, and wonder what others think about it; if anything at all
