If you look at the files you seem to have encoded with the oneliner
from my prev. message (with "mediainfo" for example) you should see
that the mp3's have variable bit rate. That's, IINM, and hopefully,
one way to keep silent parts of a song existent and silent, and the
louder ones just as loud as they are.
I don't expect variable compression to affect audio dynamics, but it
will allow for smaller files when there's less complex audio to
compress. Low bitrates just try to throw away too much data, and the
less bits you have to play with, it's going to end up including some
noticeable audio that gets thrown away.

I don't use Audacity for reencoding of existing files.
Me, neither, most of the time. Most of the audio that I'm dealing with
is stuff that I've recorded myself. So I've created a project in
Audacity, and saved it out as WAV files for all-purpose future work,
and saved compressed audio to pass on to other people. MP3s being the
worst, but easiest handled by most people. Flac can be a pain, it's
support isn't as wide, and you may need to pick a different container
file to hold the flac data, depending on the player. But if I wanted
non-lossy compressed audio for my own purposes, it's a good choice.
I rarely ever re-encode/re-compress files, because it's such a chore
and brings its own sets of problem (as has already been discussed). I
tend to make several versions from the get-go.
I'll have a look at your notes, but my comment about continuous track
playback is about audio that traverses across tracks, and needs to do
so uninterrupted. No clicks, no fades, no interruptions to the beat of
a song, a silent join. MP3 is not very good at that, and neither are
