Delete Music File Metadata Tag

How do I delete a metadata tag from a FLAC file or MP3 ID3 tag? I can use mutagen to edit information, but how would I delete a single portion of information?

I need to delete a tag entitled fmps_playcount, but not the rest of the metadata.

Solution

  • For ID3 tags you can remove a frame with delall. For example:

    >>> print audio.pprint()
TPE1=Agalloch
TALB=The Mantle
TRCK=1/9
TIT2=A Celebration For The Death Of Man...
TCON=Metal
>>> audio.delall('TCON')
>>> print audio.pprint()
TPE1=Agalloch
TALB=The Mantle
TRCK=1/9
TIT2=A Celebration For The Death Of Man...

    For deleting the FLAC metadata (I do not have any FLAC files to test this on), I have a good feeling about:

    >>> del audio['tag_to_delete']

    Since the help documentation has:

     |  __delitem__(self, key)
 |      Delete a metadata tag key.
 |      
 |      If the file has no tags at all, a KeyError is raised.
