If I use Mp3tag to view a WMA file that has multiple Artists, Composers, Conductors, Genres, etc. set in the metadata... it seems to read it, unlike most badly written utilities. Good. For example, for multiple Artists... Mp3tag shows the multiple entries as:
ARTIST={name 1}
ARTIST={name 2}
ARTIST={name 3}
However, when I save the tag... it loses all the multiple entries. Bad. Also, the remaining entry is not even the first entry that was in the original metadata... as I'd expect. (So, it seems the order isn't being preserved either.)
This is causing some chaos with my tagging. I lose metadata if I use Mp3tag to edit. Tested on the non-beta... and v2.36f.
