Starting a new thead because the drift is pretty big, and

The quick question is: How fast does how much of
a library change?
Without doing any analysis, I would guess that the files in my library
are extraordinarily fixed. Nearly read-only from the start, and
definitely read-only after a month or two.
I'm guessing, but I would expect that 99% of the CDs' FLAC files
are never adjusted at all after I get the tags close.
This is clearly not like traditional IT backups, where
there are lots of changes to most of the files.
Seems to me that this should drive different tools and
criteria in the backup system.
Ideas?
A different use case is the "slow creep" user. I want all the tracks
in my iTunes library to be rated; however, I don't have the patience to
sit down and rate them all. So, my iPod syncs with a "fifty random
unrated songs" list, which I listen to while commuting; I rate songs as
I hear them. Every couple of days, I get on the order of 50 songs
changed (slightly! just the ratings!). Most other tags are closer to
your use case: Now that I've got them the way I want them, they almost
never change.
Yet another use case is the user who hasn't yet figured out exactly how
they like their library tagged. This user will occasionally (probably
rarely) change tags across a significant fraction of the library (e.g.
changing how multiple artists are represented; changing how multidisc
albums are represented; adding composer information).
In all cases, I think there's going to be a gradual accumulation of new
files.
I suspect your use case is the most common. These other two are
getting closer to a "standard" backup scenario.
