[mythtv-users] CD Artist-Title-Track Information Incorrect

[Jim]

In an attempt to improve my understanding of the problem with the CD 
information, I reviewed the mythtv mythmusic plugin source code. I can 
see in cddb.cpp where a change was made to the URL used for the CD 
information look-up. Lines 28 and 29 are as follows:

//static const char URL[] = "http://freedb.freedb.org/~cddb/cddb.cgi?cmd=";
static const char URL[] = 
"http://freedb.musicbrainz.org/~cddb/cddb.cgi?cmd=";

Using cddb-tool for query and read of the two sites, and using a number 
of CDs as test cases, I've found the correct information can be found 
via both freedb and musicbrainz. However, there are often more inexact 
matches to be processed in the output from musicbrainz. In the instances 
where myhtv currently fails to display the correct CD information it is 
because the correct choice is not selected from the list of inexact 
matches. Also, musicbrainz does not as frequently provide the correct genre.

This leads me to a couple of questions:

1) What drove the change from freedb to musicbrainz? Is one expected to 
be a longer term solution, have a superior database, etc?

2) Would switching the URL back to freedb instead of musicbrainz solve 
the problem I encountered? Or has other code been modified in 
association with the change to musicbrainz.

3) If musicbrainz needs to be used as the primary source, could freedb 
also be contacted and its output used to disambiguate when musicbrainz 
supplies a list of inexact matches?

I don't know enough about programming to fully comprehend what else is 
occurring in cddb.cpp, or to make these changes myself. Hopefully these 
notes can help in some way address this topic.
