This program can easily give your mp3 more sane names than MUF67EHF[0].mp3. It extracts the artist and title and from the ID3 tag, and suggests a new filename. Even if there is no ID3 tag it will try to make the filename prettier by, among other things, turning underscores into spaces.
Simply drag all your files onto the white area. If the program successfully reads the ID3 tag it will suggest a new filename and check the checkbox beside it. If not, it will still suggest a new filename, but not check the checkbox.
Then click "Change checked filenames", and the new filenames (with checkmarks beside them) will be used and the list emptied.
I made this for my own use, so it doesn't have maximize/window resize and similar stuff.
