Public bug reported:
EasyID3.RegisterTextKey('comment', 'COMM') actually defines a frame
called 'COMM::XXX', which can't be retrieved by the same name.
You can set this field as follows
>>> e = EasyID3()
>>> e['comment'] = 'a comment'
>>> vars(e)
{'_EasyID3__id3': {'COMM::XXX': COMM(encoding=<Encoding.UTF8: 3>, lang='XXX',
desc='', text=['a comment'])}}
but attempting to retrieve it causes a KeyErrror:'COMM'
Code:
>>> e['comment']
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3/dist-packages/mutagen/easyid3.py", line 213, in
__getitem__
return func(self.__id3, key)
File "/usr/lib/python3/dist-packages/mutagen/easyid3.py", line 121, in getter
return list(id3[frameid])
File "/usr/lib/python3/dist-packages/mutagen/_util.py", line 536, in
__getitem__
return self.__dict[key]
KeyError: 'COMM'
As a workaround, if I define a second text key
>>> EasyID3.RegisterTextKey('comment2', 'COMM::XXX')
I can now retrieve the original tag
>>> vars(e)
{'_EasyID3__id3': {'COMM::XXX': COMM(encoding=<Encoding.UTF8: 3>, lang='XXX',
desc='', text=['a comment'])}}
>>> e['comment2']
['a comment']
Expected behaviour: e['comment'] returns 'a comment'
