Another problem with static files that you randomly load is that they inevitably show different changes depending on the developers settings - if I the files into Picard, *all* of them (even the tagged ones) will be changed. On the other hand, not all of those changes are results of my settings, the release group type of "Dark before Dawn" has changed between the submission of this pull request and now. So any change one sees when checking any file could be caused by changes in ones own settings, differences between ones own settings and those of the one who maintains these test files and/or changes to the data on MB. As such, at least I would never check the files if the tests, that provide a controlled environment, pass.
