MusicBrainz medium titles are incorrectly used as release titles

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Select a CD which has a medium title in MusicBrainz that is non-empty and 
different from the release title. Examples include the first CD of Metallica's 
Garage Inc 
(http://musicbrainz.org/release/89e78894-c0e6-3995-b69a-18938e9933f5), and both 
CDs of Tripod Live: Feghmaha 
(http://musicbrainz.org/release/6ae16372-c623-417c-8e61-f338ecdb17f3).

2. Open the CD in XLD and fetch the metadata from MusicBrainz. 

How about the reproducibility (always, sometimes, rarely, ...)?

Always.

What is the expected output? What do you see instead?

I expect XLD to use the MusicBrainz release title as the album title, 
displaying it in the metadata editor and using it to construct output filenames 
that use the %T placeholder.

Instead, XLD uses the MusicBrainz medium title.

What version of the product are you using? On what operating system?

XLD Version 20130127 (142.3) on OS X 10.8.2

Please provide any additional information below.

The attached logs are from rips of the releases mentioned at the start of this 
report. I used a custom filename format of "%f/%A/%T/%n. %t".

It is an intentional behavior, but media titles should be always ignored in 
your opinion?

Not ignored, but treated as distinct from the release title. Otherwise, the 
only tag linking tracks from different discs of the same album is the 
MusicBrainz Release ID.

What about writing the media title to the disc subtitle tag, as done by 
MusicBrainz Picard 
(http://wiki.musicbrainz.org/MusicBrainz_Picard/Tags/Mapping)?

For those who want the media title in the filename, perhaps it could be exposed 
via a new custom filename placeholder.
