Picard is the next generation MusicBrainz tagging application. This new 
tagging concept is album oriented, as opposed to track/file oriented like 
the ClassicTagger was. Picard is written in Python, which is a cross-platform 
language, and makes use of cross-platform libraries - this allows the same 
code to run both on Windows, Linux and Mac OS X.

Requires mutagen and optionally but recommended fftw and libofa
used for fingerprinting the songs for automagic tagging
