In some CDs, most often in classical music, we find a "chapter", which characterizes the "theme", for a bunch of tracks.
For example, see here:
As you can see, there are 2 "chapters", devoted for the 2 CDs in this box.
Act One: "When Cats Are Maddened By The Midnight Dance"
Act Two: "Why Will The Summer Day Delay - When Will Time Flow Away"
Now, suppose, that I do not want to have 2 dedicated folders for those 2 CDs, where I enter this information.
I would rather, include this information in the MP3 metadata.
How would you solve this issue?
