When I go to mass edit tags, say Album info, on like a group of mp3 tracks, SOMETIMES, it doesn't work (the mp3 tag software shows the newly added album name BUT file explorer/windows explorer and Itunes doesn't show the new album tag on any of the files) and what's worst, after I save the new album info, I can't play the mp3 anymore in Groove or itunes, (but it'll still play in VLC).
Only when I delete the Album tag will the mp3 file be playable again in Groove.
This only happens for some mp3 files, not all of them. Others the album tag saves just fine and I can upload into itunes no problem.
All of my files have extension .mp3 so I'm not sure what is going.
