Software :: Thoughts On Reorganizing MP3 Collection?

Last spring I graduated college. I lived in a party house, and being skilled in computers, I decided to build a media center for me and my five roomies. The thing worked great; MythTV for television, and a thin client in the kitchen to DJ the music. I had a samba share available so my room mates could just dump their music collection from their machines on to the media center. Adding new songs was their problem, and not mine. As you can imagine, nobody really wanted to organize the music to well. Many of them just dumped in the tunes and then searched for it in GMPC (a great interface for MPD by the way).

So over a year later, I have 150GB+ of music which is mostly unorganized. I need a way to put some order to the chaos... I tried using EasyTag for a while. Don't get me wrong, it's a great program. But sorting through every directory and song would take me DAYS, time I just don't have.I need a way to SAFELY rename and organize all of the music into a logical file structure. My initial thought was to just connect an external hard drive, copy it all into iTunes on some laptop, and then recopy the then organized iTunes database back onto the media center.
