I think I figure out why the info is not being retrieved by some albums. That will surely help you to fix the problem I'm having with some albums.
Take Bahamut Lagoon Disc 2 as a good example:
http://vgmdb.net/album/2702 Disc 2
The Disc 2 as follow:
This is the right tracktime.
01 2:17
02 2:48
03 0:21
04 0:18
No matter what I was doing I could not get the info from VGMdb freedb server, even though the tracktimes were correct.
So what did I do?
Simple I just changed the track 04 to 0:17, and there I had it, now I know the problem exactly.
Some albums do not work if the tracktimes match it precisely.
I tried with the album
http://vgmdb.net/album/10278
The correct tracktime is as follow.
01 CHRONO TRIGGER ~Orchestra Version~ 2:08
02 CHRONO TRIGGER MEDLEY ~Orchestra Version~ 4:11
By the example above I could not get the info from VGMdb server.
It has only 2 tracks. so my first test was "if I edit only track 1" for example.
01 CHRONO TRIGGER ~Orchestra Version~ 2:07
02 CHRONO TRIGGER MEDLEY ~Orchestra Version~ 4:11
So what did I do?
Simple I tried it again by editing the tracktime of the track 02 as well for example:
01 CHRONO TRIGGER ~Orchestra Version~ 2:07
02 CHRONO TRIGGER MEDLEY ~Orchestra Version~ 4:10
By the example above I could get the info from VGMdb server no problem.
So what is the catch?
Simple it looks like some albums will not work if the tracktimes are precisely correct, mostly are albums with less than 8 tracks. I'm still testing.
