As someone who has been thinking about a system to organize my improvisation band's rehearsal recordings I have made many of the same realizations. Only with us some of the points are even wilder, because for us "a song" is the abstract concept or idea for an improvisation rather than a fixed set of notes played in a fixed way in a fixed order. Sometimes that idea can be a word, sometimes it can be very precise sound settings, high-level structural ideas, a set of lyrics, rhythmic patterns, melodic themes etc. So any given recording can contain within itself any number of songs (including zero). Those songs can exist or not. And my conclusion for our case was that there is no automated way of deciding which is which, as at times it could be hard even for us ourselves.
