Read an mp3 file (track length, bitrate, etc.) and access it's tag:
  if eyeD3.isMp3File(f):
     audioFile = eyeD3.Mp3AudioFile(f, self.opts.tagVersion)
     tag = audioFile.getTag()

Specific tag versions can be selected:
     tag.link("/some/file.mp3", eyeD3.ID3_V2)
     tag.link("/some/file.mp3", eyeD3.ID3_V1)
     tag.link("/some/file.mp3", eyeD3.ID3_ANY)  # The default.

Or you can iterate over the raw frames:
     tag = eyeD3.Tag()
     tag.link("/some/file.mp3")
     for frame in tag.frames:
        print frame

Once a tag is linked to a file it can be modified and saved:
     tag.setArtist(u"Cro-Mags")
     tag.setAlbulm(u"Age of Quarrel")
     tag.update()

If the tag linked in was v2 and you'd like to save it as v1:
     tag.update(eyeD3.ID3_V1_1)

Read in a tag and remove it from the file:
     tag.link("/some/file.mp3")
     tag.remove()
