Mutagen adding year metatag to an MP3 file?

Question

I'm using EasyMP3 from mutagen to add metadata tags to an audio file. But in EasyMP3 the year tag is not defined so I am getting an error saying year is not a valid key.

The following code demonstrates the problem:

from mutagen.mp3 import EasyMP3

tags = EasyMP3('test.mp3')
tags['title'] = 'Some title'
tags['artist'] = 'Some artist'
tags['year'] = '2022'
tags.save()

This is the error:

mutagen.easyid3.EasyID3KeyError: "'year' is not a valid key"

Since I just started using mutagen I don't know much about its other instances. How can I add the year metadata tag to the file?

Folllowing the documentation of EasyMP3 it returns a EasyID3. Not all tags are supported out of the box but you can register others you might need using RegisterKey (and more related functions).

For year it should be possible to use EasyID3.RegisterTextKey("year", "TDRC") - check id3v2.4.0.

For your example, the following code would work:

from mutagen.easyid3 import EasyID3
from mutagen.mp3 import EasyMP3

EasyID3.RegisterTextKey('year', 'TDRC')

tags = EasyMP3('test.mp3')
tags['title'] = 'Some title'
tags['artist'] = 'Some artist'
tags['year'] = '2022'
tags.save()

for EasyID3 the tag is 'date' or 'originaldate'
