Simple script that I wrote to fix encoding of id3 tags in my mp3 collection

id3_fix.py

import os

import click
from mutagen.easyid3 import EasyID3
from mutagen.id3._util import ID3NoHeaderError


@click.group()
def cli():
    pass


@cli.command()
@click.option('-d', '--directory', help='Directory with mp3 files')
def encoding(directory):

    for root, dirs, files in os.walk(directory):
        for file in files:
            file_path = os.path.join(root, file)
            try:
                f = EasyID3(file_path)
            except ID3NoHeaderError as e:
                print('Error reading file:', file_path, e)
                continue

            for name, value in f.items():
                try:
                    new_value = str(bytes(value[0], 'iso-8859-1'), 'cp1251')
                    print(
                        'Fix id3 tag "{tag}" value "{value}" with new value "{new_value}"'.format(
                            tag=name, value=value[0], new_value=new_value
                        )
                    )
                except (ID3NoHeaderError, UnicodeEncodeError):
                    pass
                except ValueError:
                    pass
                else:
                    f[name] = new_value
            f.save()

    cli()
