I dont get it, does tha tag show up in foobar's file info or not , or are you only going by whether the plugin displays it ?
When it shows up in file info, I also correctly see it in the plugin.
QUOTE
How are you loading the files, with .fpl playlists ?? Or are they staying permanently in foobar's playlist ? I.e. does clearing foobar's playlist, (maybe restarting it) and adding a file (with "LYRICS" field) to playlist have missing lyrics field ?
I have a permanent single playlist, yes. And completely clearing it and reloading the folder(s) didn't help.
QUOTE
if its apev2 it will say something like "APETAGX"
That's it: at the beginning of the tags list I have this string: APETAGEXÐ
QUOTE
If reload file info kills the info too, it suggests its not stored in the file (or foobar isnt reading it).
I'd say the latter: I can't believe that the tag is removed by simply copying the file.
QUOTE
[current playlist is stored on exit (i think) to a .fpl file with all metadata]
Right, but it looks like culprit files have no lyrics info in the fpl.
QUOTE
open the file info box, add a field with a random name (NOT something like artist that can go into other tags), click update, and press reload file info. Does that dissappear ?
Yes.
QUOTE
Apev2 tags: I mean the option under standard inputs in foobar.
Thank you: I have "APEv2 and ID3v1" here and "Remove ID3v2 tags..." is NOT checked.
QUOTE
Is there any reason you dont have the database enabled? Maybe you should try enabling it..
Er... I simply haven't investigated this option yet...

I can of course try it, but I'd rather fix this strange behaviour before...
QUOTE
Does it also happen on a clean install?
I'll try this tomorrow if/when I get my hands on a "clean" machine.
QUOTE
Does Tag.exe show the Lyrics info ??
It displays the Lyrics info (under the "Comment" tag, but I guess that's normal) only for the working files.
Thank you for your time, I really appreciate your help.
