This is the message popped out by Mp3tag when trying the above:
This is, of course, understandable. However, I really wish it could be work around somehow. I frequently want to edit tags of files which I'm currently listening to and currently there is no way to do it other than stopping playback. I remember Winamp was not causing any problems in that matter. Maybe there is solution on either foobar/Mp3tag side?
