Comment 4 for bug 1173749

1a) So the users can't leave the editor before fixing the malformed tags? This would be the easiest solution, but not very user friendly. The user should have the possibility to save a song every time, even when it is malformed. Anyway, a message box should point out the user that there is an error an that the song could not be used in this state.

1b) This would be the advanced version of 1a, showing the wrong tags by coloring them. Nice.

2. I don't think so. In my opinion there mustn't be any changes on any song without the knowledge of the user.
You don't know, if there is a tag too much or too less or if this is a wrong written tag or ...
The user has to decide what to do with this malformed song.
Possible actions would be: Cancel import or show song in editor. Maybe ignoring the issue would be a possibility, too.
