Ok, like many people our music libraries become a mess after a while. What i am looking for is an open source app that you point it at the music directory and it tags, and deletes duplicate copies, moves and creates a directory that is beautiful to look at, everything in its place named and tidied away. If i can't find an app, I am gonna nuke the directory. My problem was due to having it accessible on a network at uni, and people just fecked it up, i have folders with just one track in them un-named! Can the people of bit-tech save my 207GB of music in various formats and bit-rates. (Yes its mess!)
The Godfather and MP3tag are the two I use on a regular basis. The first one to sort out filing all the music and the second one to make sure that the tags are in a reasonable state. Both free.
I love mediamonkey, but it won't do what you want (not even the paid up gold). But it could save what's good if you're prepared to the spend the time. If you want something to sort out and tag up unknown mps in unknown folders then you're going to need some real clever tricks to tie into Sound Hound or something similar. Mediamonkey will browse your collection by folder, and you can select any number of files at once and autoarrange by any schema you choose. But... It's still manual, you have to look at things and make the call on what is good and what is not. I used it to sort, tag and add covers to my "fairly messy but not too bad" 300gb music folder. It still took f'in ages, but was worth it. Still quicker than re-ripping, which on old obscure stuff still needs manual clean up anyway. So try media monkey, lets face it you're going to need something to keep that sucker clean no matter what you do with it now
i just started looking manually in the directory, things have been moved around with duplicates everywhere. Its just caused me to have a mental collapse. Time to nuke it and start the re-rip with some heavy awesome software. Its not so bad, there really is some weird and mental music in there that others added, but its mostly 128kbps, wrist slitting quality! FLAC library and mp3 320kbps libraries to be built
Picard musicbrainz is very good. I use it to organise my collection. http://musicbrainz.org/doc/PicardDownload Also this thread on their forums has a selection of scripts to automatically organise your music http://forums.musicbrainz.org/viewtopic.php?id=514
