What music organizer do you all use to tidy up your music forlders? What works well and why do you like it?

It works very well with eJukebox. I like it because the tag editor and the file organizer are well done: Powerful but very easy to use, just like eJukebox!

ID3-TagIT 3

A program for editing, adding, or deleting ID3 TAGs in MP3 files. Single file and batch editing are both supported. Edit one, ten or all your MP3 files at once. ID3-TagIT has many functions to help you achieve your goal as quickly as possible. ID3-TagIT is - in contrast to many other editors - able to read information from the directory structure and put it into the TAG, organize files into folders, handle several comments and genres in the ID3V2 TAG, and every function is available for ID3v1 and ID3v2.

I use MediaMonkey (http://www.mediamonkey.com/)

It's very user friendly, good looking UI, automatically look up the data. It has a good explore(file structure) where you can move around how you want (location, title,album artist, etc. ).
I was trying a few others before but they were not so easy, so now I stick with mediamonkey.
Its also having a player (with partymode), but still - ejukebox rocks

I also use mediamonkey for various artists rips and album tagging.

MP3Tag is my favorite choice. Very powerful

Just change one setting in MP3Tag after install:

Tools - Options - Tags - Mpeg:
Change ID3v2.3 UTF-16 to ID3v2.3 ISO-8859-1


Ejukebox does not support UTF-16 tags so it will mess things up if you save your mp3 files with this setting unchanged. Read here: http://forums.mp3tag.de/index.php?showtopic=2798&hl=ejukebox
