Bug 184411

Description of problem:
Some discs have the same DiscID in MusicBrainz.  A really common case is where
an identical CD was released in different countries at different times, and
MusicBrainz contains separate information with the track names and album name in
each language.  Currently, if you insert such a disc, sound-juicer pops up a
window informing you that multiple CDs match it and prompts you to select the
right one.  That's all good, but the list, rather than containing each matching
CD, contains only the first option repeated every time.  I have a patch that
fixes it.

Version-Release number of selected component (if applicable):
sound-juicer-2.13.6-1

How reproducible:
Every time

Steps to Reproduce:
1. Insert a disc whose DiscID has multiple matches in the MusicBrainz database
(http://mm.musicbrainz.org/showcdtoc.html?id=147937 is an example)
2. Observe the prompt
  
Actual results:
sound-juicer prompts one to select among a list all of which is the same, the
first listing in the database.

Expected results:
sound-juicer should prompt one to select the correct album from a list of
different choices which match those in the MusicBrainz datebase

Additional info:
I have a patch that fixes it.  A call to MBS_Back should be changed to
MBS_Rewind, since it's not clear where one will be in the MB data.  MBS_Rewind,
rather than going up one level, resets to the state immediately after the last
query.  That's what we want.  See http://www.musicbrainz.org/client_howto.html
