Where / how do these people
get the specs? If they can get the specs then so should I. Can you
please suggest a link / a book or a something where I could get
developer specs for the mp3 format?
I had once worked on a utility for automatically updating tags from
musicindia website.... I found this opensource java based project to
be a very good starting point.. it has classes for MP3 files IDE tags
you may also look at KDE multimedia sources if you are comfortable with C++
