I'd say that zero out of these 15 will be in CDDB without some need of fixing up...


Yeah, it depends on how picky you are.

To me, I get about that ratio (perhaps 1 in 100 discs doesn't need touching up). But that's usually because I'm picky about things like capitalization, adjusting the Genre to my liking, and making sure the Year is entered. If people don't care about those things, then the CDDB is actually quite useful.
