Ahh, yes I found the setting in VLC preferences.  Now set to "Manual".

I don't see how it can be using CDDB or kin, though, from the description
in WP.  The ID seems to be formed by the length and order of tracks
in an album, but my files are all single tracks, and probably only
approximately the length of the original as I usually put a brief
silence before and after.  I rather hope it's not using a Shazam
type audio signature derived from the track itself!

Veering a bit off-topic, I listen a lot to Radio Caroline and its Flashback
(again usually via the Pi) and they both use the 'ACRCloud' service to
provide a playlist of their tracks.  This often staggers me completely
with its ability to accurately name the most obscure song and then,
equally strangely, to quite fail to identify the most familiar one!
(It does use a signature derived from the first few seconds of audio.)
