I have a Phil Collins album. I prefer to store it in 3 folders (CD1, CD2 and CD3).
The Discogs release ID is 9195914.
MP3TAG retrieves the metadata and displays it correctly, but for CD1 only. For CD2 and CD3, the problem is MP3TAG loads the whole album in the left pane, but on the right pane it is the content of CD2 or CD3 folders only. So if I proceed with sync, the metadata of the first song of CD2 will be populated with the metadata of the first song of CD1, down to the last song, unless of course I manually move down all 15 songs to the position 16 and below, which is not a pleasant solution.
If I was able to delete the unused metadata from left pane, it would be much easier.
