Hi, I'm unable to edit details on unprotected MP3 files using Windows 8 phone plugged into Windows 7. I've tried doing it using both WMP, and the file system. (although I guess it's not regular usb mass storage.) WMP shows the edit option greyed out. I supposed I could try takinig out the SD card and editing the files directly? Is there any other way?

I've seen many posts on this topic but nothing has worked, including 3rd party utilities. I thought I'd try here in case there is a WP8 specific solution.
