It's eyed3 capable of acces all mp3 'standard' tags besides more common ones as 'title 'track'?

Question

I succeed to tag the more "common" tags in mp3 files and the user-formatted ones. But other standard ones as 'copyright', 'engineer', 'composer', 'encoded by', 'language'. are no showing (for example in EasyTag or other audio programs) My lines are :

     t =Tag()
                t.artist = TAGS['AUTEUR']
                t.title = TAGS['TITLE']
                t.album = TAGS['ALBUM']
                t.genre = TAGS['GENRE']
                t.recording_date = TAGS['YEAR']
                t.track_num = TAGS['TRACK']
                t.publisher = TAGS['PUBLISHER']
                t.disc_num = (1, 1)
                t.user_text_frames.set(TAGS['CDID'], u"CD_ID")

 #These stick OK


                t.engineer = TAGS['ENG']
                t.copyright = TAGS['C']
                t.composer = TAGS['COMPOSER']
#no showing
                t.save(AUDIO, version=ID3_V2_3)
#I also test with version=ID3_V2_4 but no cigar.

It's eyed3 capable of access these tags?

Answer 1

OK, really needing the 'Copyright' tag, i switch to 'Mutagen' module

All tags i needed are there, without the adding extra metadata creating 'user text frames' to store other important information.

Some ful recipe code to use Metagen here: http://code.activestate.com/recipes/577138-embed-lyrics-into-mp3-files-using-mutagen-uslt-tag/

Forthe copyright, just: ...........

from mutagen.id3 import ID3, TCOP #... more imported tags here

try:
    tags = ID3(mp3file)
except ID3NoHeaderError:
    print "Adding ID3 header;",
    tags = ID3()
#... more tags        
tags["TCOP"] = TCOP(encoding=3, text=u"""All rights reserved.

tags.save(mp3file)
