While downloading music (for archive purposes only, of course) I always run into folks that get a bit too creative with their naming conventions:
01-dropkicking_murphys-bar_room_hero-FANBOI(2008).mp3
So of course renaming these files is a royal pain in the fanny. Finally tired of half-ass programs or doing it manually, I finally found a program that could do everything. It's also 64bit Vista ready.

Free and very powerful. I told it to remove the first three characters, capitalize the first character of every word, remove the '-fanboi(2008), replace _ with spaces and add a space before and after - . And bingo, it did it. Nice.
