Max:
Thanks for getting to the bottom of the 24 bit bug (3299). Will the fix go
into 0.17 git?
I'll test it this weekend with all the USB stuff I can grab.
Where do I look in memory to see how much space is used by a large
collection? I'm dealing with one collection that is almost a Terabyte, but
also has every tag as a long entry: EG. Title Rachmaninoff 3rd symphony
second movement in b flat opus 27 performed by . . . . etc. in just the
track name. Would this make the system take longer to process and navigate?
It loads (it seems to take about 10 minutes to load from nothing) and runs
but some commands seem a little sluggish.

The option has been deprecated since MPD 0.13. Ever since the
"update" command was added, --create-db has not been useful anymore.
It was a kludge from ancient times.
You can still simulate "--create-db" by deleting the database file,
but I do not recommend that, because rebuilding it from scratch takes
a loooong time.

Submit a bug report.

The "update" command. It is very quick: it does not open files that
have not been modified (time stamp). It removes database entries of
deleted files. And it works without restarting MPD, while playing
music.

There is nothing special about having a large database. There is
still the "problem" that MPD needs to have the whole database in
memory, but I have not heard of any user that memory usage is a
serious problem. My database for 300 GB of music has 6.5 MB.
