MP3 collection manager
Dear Lazyweb,

I have a lot of MP3s. A *LOT*. They're on a network share. I had originally organized them using iTunes, (Artist/Album/Song directory and file structure) but now that they're on a network share, iTunes refuses to add them to its collection and manage them.

My required minimum features:

-Windows (sorry, no Mac at home)
-Can handle 100,000+ songs

I don't care if it has a built-in player- I just need this to organize the files and tags.

Extremely nice to have features:

-Moves MP3s based on tag changes (like iTunes does when you let it manage your library)
-Has no problem with network drives- the MP3s are on a file server (iTunes on Windows refuses to work with MP3s that live on a network drive). This is not absolutely required, as I can try and fool some programs into not seeing the network drive as a network drive... iTunes just seems to be extremely uncooperative when it comes to this.

Media Monkey looked OK, and it pulled in all the MP3s from the network drive. Unfortunately, it also went down in flames once I tried to actually start working with making changes to song tags- I think its internal file database wasn't able to work very well with that many songs.
