Updating collection: What is 'comp: False -> True'?

I’m updating a collection that I recently built using Beets and I’m seeing the following all the time:

comp: False -> True

Is that the fabled 'comp flag’? Why is it appearing on every track?


Yes, it should tell if an album is a compilation. What it tells in reality is if the first albumartist is ‘Various Artists’ (see beets/autotag/__init__.py, line 181) which soesn’t entirely make sense, I mean, there is an albumtype in MuiscBrainz that is called ‘Compilation’, why not take it directly?

Actually, it shouldn’t appear on singletons.
