I wrote this small program in
order to get rid of confusing MP3-filenames like QQQys.mp3=>
My program reads the information stored in the ID3 tag of the
mp3 and renames, for example, all mp3s in a directory. Of course,
my program also lets you change them one by one and offers you
a filename-mask to get filenames like "Title - Interpret
- Album.mp3".
