The program doesn't require installation. Simply unzip the files to any folder and you're ready to use it. You can drag and drop MP3 folders and files onto its interface and then select the rename option you prefer among three different possibilities. Also, the program can apply upper case to the first letter in all words, remove numbers and replace certain text strings, among other options. During our tests, the renaming process hardly took more than a few seconds and results were excellent.
The great thing about MP3 Fox is that you can make a preview before actually applying the changes. The downside to it is that annoying message that appears every time you rename files, asking you if you're really sure. But I guess that's a tiny flaw that I can accept in such a simple, great program.
Easily rename your MP3 files according to their ID3 tags.
