[LinuxUsers] GPL'd MP3 tagging tools

[Roger E. Rustad, Jr]

I've been looking for a good open source MP3 tagger program, but haven't 
found any that I've really liked.  Thus far, this has been the only free 
  (non GPL) one that I've been using:

It does most of what I want fairly easily, but I would like to some 
better F/OSS tools, particularly ones that work well in bash.

Anyone try any of these from Sourceforge?
