Description:

This is a simple Python module for retrieving and setting so-called
ID3 tags on MP3 compressed audio files through an object-oriented
interface. MP3 players generally use this simple information for
display track title, artist name, and album title while playing the
sound file.

ID3.py supports ID3 version 1.1, including the track number field. I
have no current plans to code up the monstrosity that is ID3v2
(http://www.id3.org/id3v2.3.0.html) but if someone wants to add that
functionality, feel free!
