I've heard this complaint before. And the solution continues to be "add it in." I'll stop here.

OS - Windows 7
When I right click on any mp3 file and navigate to Properties > Details
I can't find the details of Artist, Album Artist, Album etc and hence can't edit to organize my music.
This happened after I upgraded my PC from Windows XP to Windows 7.
I was able to update all the details of any mp3 files when using XP.
I never had any third party Tag software.
