[mb-style] redundant ExtraTitleInformation

[Jan van Thiel]

Hi,

I feel that 'album version', 'edit', 'original', etc. are all
remix/version names (don't have a good name for this, please think of
one so I can add it to a new guideline proposal), comparable to 'Some
Crazy DJ mix'.

Consider the following two releases:
single:
1. Some Song
2. Some Song (album version)
3. Some Song (Some Crazy DJ mix)

album:
1. Some Song
...
12. Some Song (single edit)
...

Why should we remove 'album version' on the single, but not 'single
edit' on the album? I consider them to be remix/version names that
just do not have a given name like 'Some Crazy DJ mix'. And in the
context of the release, 'album version' is not redundant at all. And
if it's written on the sleeve, it should be in the database. It's just
unavoidable to have different names for the same track on different
releases.

In my opinion.
