Some ID3 fields in MP3 are not seen by Win 7 even though they are in Foobar. Specifically the discnumber is not being passed through properly sometimes. But sometimes it works. Other fields such as composer also fail when the discnumber fails. I have tried various things such as removing non ID3 fields, re-entering the discnumber... and the only way to make it work is to manually enter "part of set" in windows as 1/2 for example. But then Win truncates all of my other fields, and I have to put them back. It is most annoying to do this.Is this something that needs to be fixed in Foobar, or is it a windows problem. If a win problem, what is the best workaround?
