I saw the how to edit your id3 tags in the user submitted tutorials section, and was goingto reply there but decided i dont wanna cause too much trouble.

anyway, if you have any size of mp3's this is the program for you. This thing can do it ALL.

change id3 tags
arrange by artist/group and put into seperate folder
rename according to what it finds on the inet
etc etc etc etc etc etc
AND you can even write your own scripts for it if it cant do enough for you. It is a definent must use and se if you are an avid collector of mp3's
