Hey another Peice of software that is kinda relataded to this is Tag&Rename, it is cracking for organsing huge amounts of mp3's even being able to get all the information for albums not only of CDDB but also of off allmusic.com. This is one hell of a powerfulll pice of software and Ive just spent the last 9 hours fully organsing my mp3's into such a good state that I can use mood software to make playlists on the fly now. if ya interested:
