Thanks for the reminder. I've been resisting just out of principle, as I vastly prefer working with open-source tools whenever possible, or at least freeware with a decent community of support like MP3Tags. If I consistently hear that a commercial/shareware tool is really head-and-shoulders superior to the point that it's indispensable then I'll consider using them, but will go to a surprising amount of effort to kludge workarounds together to avoid them if at all possible.
