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.
