Sure. What I have in mind is this:
Let's say I am playing a playlist that has a specific selection of music. Example: genre: classical; rating: equal or greater than 4. I would like to randomly shuffle by album of those selected track, but only those tracks.
Why? Not uncommon, for example, for a recording of Beethoven symphonies to include one work I want to hear and one I don't. If the album shuffle mode expands to full album, then the work I don't want would be played.
Think of this example playlist:
[Media Type]=[Audio] [Genre]=[Classical] [Rating]=>=4 ~sort=[Album],[Disc #],[Track #]
I would like to preserve the order of tracks within the album, but randomly shuffle the order of the albums
