Thanks for the help. I will look into these options. But, the interesting thing is that MC itself behaves perfectly well in this regard, with a little care. All of my albums are correctly organized in the library, largely by ensuring that Album Artist is filled out. For example an album by one singer who has a guest appearing on each track is easily sorted by ensuring the primary singer is the one listed in Album Artist (otherwise each track appears as a separate album). The only issue I am having is that Windows stores each of the tracks of such an album in separate folders, so when I copy that music on to my DAP, it no longer appears as one single album. What I could do, very simply, is to make a copy of the tracks into a folder (with album name, possibly as sub-folder of Artist Name) on my desktop and use that one to copy into the DAP, then delete it, right? Only thought of this as I am typing...
