Here is a program I made on account of a friend who just moved to Linux. It's sortof ASCIIish because it outputs any information to a console, no fancy GUI here. Anyway, long story short I wrote a program for him to automatically name several thousand .mp3's based on Artist, Title, and Album, which in turn is a very useful program if you ask me. Example:
Artist - Title - Album.mp3……(New Filename)
All that needs to be done is stick the file bot (MP3_ReNamer.exe / MP3_ReNamer) into a dir with MP3's in it that you wish to rename. The bot will stream though the MP3's and load their trailers, find the right tags and rename it. If the bot doesn't find at least two tags it will skip the file and go to the next with out renaming it. That's about it. =)
This is an automated renaming tool. It is not guarantied by any means not to cause damage. Use at your own risk, and make sure you back up any MP3s you wish to rename in case of a failure. I will not be held responsible for any miss use of this program. Now warned, enjoy the software.
