Thanks for the suggestions, everyone. Looks like none of the taggers listed will submit multiple "albums" to freedb at the same time, or batch them, or queue them - at least not that I could find. I must submit each album individually. A bit surprisingly, I'm able to do so faster and easier with Foobar than any of the tagger apps I've tried so far. So I guess at this point, after one final search online, it's time to slog through submitting each and every studio release individually to freedb. No problem, submitting 400 albums individually won't be tedious or anything... :ugh:
