Sonos thx. for creating the Android Mobile Device streaming capability the only thing it needs now it the Folder View. Music genres, etc. are nice for iPhone folks but I (and possibly most Android users) like to categorize/organize my music (on my mobile device) into folders. Allowing parent level (down thru sub) folder playback would be icing on the cake. Similar to what the desktop/mobile controllers currently have (Music Library\Folders). Please add this capability to the next Android Mobile Device streaming update.
