I know this probably won’t help much as I’m on WL9, but I used this function twice earlier today and it does appear to work; there is no way to verify that the actual submission to freedb has been accepted unless you try the import in some days and find that the names are recognised. I haven’t used 8.5 in a while but I do know that it did work back then, perhaps check that you have the latest update (8.5.30/31) installed and try again? Some freedb issues were addressed in 8.5.10.
