With my limited experience on the matter, I'd advise you against Baloo
for multimedia metadata.

For 2 reasons:
 - You will need to manage streams metadata, from online content, and
   you'll need Taglib parsing anyway, duplicating the code
 - Multimedia metadata is weird, and can be inside files, outside, or
   using some weird unstandardised conventions. I doubt that will fly
   well with Baloo.
