Yep 2 all !
2 databases, one is my working database (on a external memory), the other my backup.
I use soft like Rekordbox, Traktor. So the tags are constantly changing...
I was looking for a solution to keep all the databases synced and I discover this:

Can I limit on particular tags only? like %ratings mm%, ...
Thanks by advance !
and thanks for mp3tag, this is a really nice tools
