There is a real issue here. I use dBpoweramp for ripping, rather than MC, because DPBA gives access to more useful tagging databases. Freedb is totally useless for classical music . . . apparently it is used only by folks limited to itunes and ipod and their lack of fields. (The source of the "lack of standards" was Apple's crass decision to throw anything but pop music under the bus to make its i-system simple.) Of course it's true that standards are lacking or not always followed, but it doesn't follow that any database is good enough, nor that you can't do better.
Some databases, including Sonata and AMG, give far more useful information than YADB or freeDB for tagging classical.
