Would it be too much trouble to ask to put these in the Internet Archive as items while you’re at it?

Good idea. I haven't uploaded to IA before, but it looks like I was able to do it. I put the software metadata attribute on the files, but other than that I wasn't sure of what other metadata to add if any.

The files that were mentioned above should now be available at https://archive.org/details/freedb

After uploading the files I noticed that there were some results on IA already for FreeDB, and one of the results is even a user named freedb which I guess might be an official account of the FreeDB people.
