I have fought this battle for over a year and a half. It is time consuming and very discouraging. Here is the problem. When I add tracks to the library, the bios field fails to show its contents for about half of the tracks. I may have have fifty tracks by a particular artist, and ten bios fields may be empty. For another artist they may all be empty. Yet, for a third artist, maybe one field is empty. And for a forth, they may all be correctly filled. I spend hours correcting these omissions, using the Action Window taging tool. At some point in the future when I clear the library and import the files again, I have the same problem, but maybe to different artist. I know the information is still within the files because it shows up when I use another mp3 player.
Another issue I had was the contents from many of the bios fields would show up in the comment field. Deleting and pasting the information back to the bios field would not be permenant. Once I cleared the library and re-imported the files the problem would reappear, but not necessariarly to the same files. The way I solved this was by putting a period in each of the empty comments field.
Any suggestions on how to fix this?
(It may be unreasonable, but I want to store all data in the tags of each of the individual files. I know this is repetitive and wasteful of disk space, but that is what I want. )
