These files have a corrupt flag in them; the unreleased version of Mutagen has some
code to handle corruption of that flag because it's common, but it amounted to just
skipping over the file.

Such files should now have a much better chance of loading.

Unfortunately the file offers no clues as to its origin. The only unique thing in the
file is PRIV tags for PeakValue and AverageLevel, which I've also never seen before
(foobar uses TXXX frames, iTunes uses COMM frames, and the standard uses RVA2 frames).

If you check out the latest version of Mutagen it should be a drop-in replacement for
whatever you're using. We take API compatibility very seriously.

I have a whole bunch of such files, not only mp3's but some flac's as well. Is there
any way to fix the flag in existing files? Any small utility that can be scripted and
run aver the whole media library?  Would be nice to be able to use these files before
the updated version of mutagen makes it into the application dependent on it. Is
there an information what software (converter, tag editor?) causes the corrupt flag,
so I can avoid using it?
