Problem with jazz interpretation of chord symbol playback.
The "Jazz" interpretation feature of chord symbol playback changes the literal chord playback by substituting enhanced Jazz chords. However, the problem is that the playback no longer matches the chord symbol display—a possible source for confusion for the user.
A better alternative, IMV, is to maintain the WYSIWYG nature of chord symbols (i.e. playback matches the visual display) and simply to provide an extra feature which allows users to substitute the display of existing chord symbols with their Jazz variants. The "Interpretation" property could then be removed altogether.
