Then explain this: WHY is this happening only in the last several
MONTHS? I've been editing mp3 properties since 2007, going back to XP
and (!)-ME, and the song data that I input STUCK! What was there
different about those two and the Vista and WMP 11 that I'm using
now???

If there weren't anything different, why do you think MS released
2 or 3 or 7 new versions of WMP during that time? WMP is
second only to iTunes for doing stupid things that you didn't ask for.

And I still haven't got an answer as to why the data is disappearing
from songs ON MY MP3 PLAYER.

Because you have probably connected it to your computer several
times and your MP3 player gets "updated" with whatever mischief
happened to your files since the last update.

DUMP WMP, fix your files with MP3tag and THEN see what
happens. Else, if you want to keep fooling around with WMP
and other user-vicious applications, you're on your own.
