T&R said V1's were clear and V2's were populated (as intended), but the empeg got its info from some random text at the end of the file. I think the tag section wasn't preceeded by the string "TAG"... but I forget.

In every case of the corrupt tags, the strings "Brava Software" and "Musicmatch Jukebox" were near the bitter end of the file when viewed in a text editor. I think we know who the culprit is.
