This looks like a duplicate/linked to bug 1413821 [0], please see the discussion there as well where we stated that it needs to check if the path is within, for example for music.
/home/*/Music
/media/*/*/Music
Then use url-handler, otherwise use content-hub. This should be the same for documents, music, photos, videos etc.
Or alternatively for music (possibly photos, videos) check if it is in the MediaScanner store.
