yes i use that for the last few years but no joy I pay for it in a subscription to Apple £1 -99 a month and i'm not getting the full version of tag editorIt probably relates to the metadata in the files, if you copy individual tracks from album folders they will retain the original album name in the metadata and any player will think they are individual 1 track albums rather than a compilation.
You can set up playlists to do this, or use something like MP3tag to change the album names to whatever you want to call each compilation.
