ID3/WMA Tag—
This is a method of embedding track−re-
lated information in a MP3/WMA file. This
embedded information can include the
track title, the artist’s name, the album
title, the music genre, the year of produc-
tion, comments and other data. The con-
tents can be freely edited using software
with ID3/WMA tag editing functions. Al-
though the tags are restricted to the num-
ber of characters, the information can be
viewed when the track is played back.
