mass renaming of audio files....

i have a massive folder of music files, most of which are MP3, i need some kind of program that will go through this list of music, and automatically rename it to the correct title-artist, et cetera... i know a program such as this exists, i remember having one before my last format... it would open the audio file, create an odd type of hash from the file and look it up on the programs database of music.. anyone recall the name of that program or something simmilar?

There are many utilities that can batch rename mp3's.. here's a freebie..
