If I manually edit the fields, it will display properly within the library but not when I check the file shortly after. Apply media information changes takes its time but does not appear to be working.
One blogger's post claims WMP will not write metadata to the file which I would be very, very upset if this is true - unless someone has a plugin to try and batch export it all. However, MS support for WMP claims it will write the data over time, you can click apply media information changes to start the update immediately. I've checked the tag versions and no data is even written. The files are not read-only but I haven't checked any permissions past that, though I've had no errors.
Side note, contributing artist equals artist. Other than swapping those tags, any suggestions? To me, Album artist should equal the artist, I've setup contributing artists to be more like the remix by or featuring so and so. Unfortunately my Ford reads the contributing artists as the artist as well so it's all backwards.
