mutagen (Python 2/3 module for handling audio metadata)

Mutagen is a Python module to handle audio metadata. It supports ASF,
FLAC, MP4, Monkey's Audio,  MP3,  Musepack,  Ogg Opus,  Ogg FLAC, Ogg
Speex,  Ogg Theora,  Ogg Vorbis,  True Audio, WavPack, OptimFROG, and
AIFF audio files.

All versions of ID3v2 are supported, and all standard ID3v2.4  frames
are parsed.  It  can  read  Xing  headers to accurately calculate the
bitrate  and  length  of  MP3s.  ID3  and  APEv2  tags  can be edited
regardless of audio format. It can also manipulate Ogg streams on  an
individual packet/page level.

Mutagen  works  with Python 2.7, 3.3+ and has no dependencies outside
the Python standard library.
