I like mp3tag and I use it to edit music metadata. I can see full metadata of my music in mp3tag but if I use windows explorer, little metatdata is shown. If I check Properties of a song, the Details tab is almost empty, which should be filled with album, year, etc. that I added through mp3tag. And I can't find any rule what kind of metadata can be seen in windows explorer. Some music miss track numbers, some have wrong album names and some have no titles. What's wrong?
