My digital music collection on my NAS is arranged in a straightforward folder tree. (Thus the sub-folder of jazz music has 8 sub-folders of jazz types and each of those has sub-folders for different performers.) I would like to be able to pick a folder at any level in the tree and play shuffled contents of the sub-folders it contains. There are several android apps (e.g. Music Folder Player) that allow me to do this when I play the collection on my phone. Is this possible on the soundtouch app? If not, could the engineers please oblidge?
