I remember iTunes used to have the option to "keep music files organized" (i know it still does in its advanced Properties). When I used to edit music's artist, genre or album information. The mp3 file is automatically updated as well. But lately I've been updating some mp3s. And if I tried to open the updated mp3's Properties, under Details, the Artist, genre, and album information is not available. How can i fix this?
Added: you can try editing this mp3 file with iTunes, it didn't work on my PC
Here's a screenshot of what Im seeing after the edit.
