Having documentation for songs is helpful if you hear something you did two years before and can't remember how it was produced.
At some point you are tempted to surrender to the ephemerality of the enterprise and just give up.
Like, when you are eight songs into documentation of a 26-song LP.
The Digital Audio Workstations have a feature where you can archive old productions. Mostly it's crap, as folders get moved on hard drives, computers age, operating systems change, and dongled plugins are no longer accessible.
Live for the moment, man.
