Having just read the Beosound 5 user guide I am a bit baffled that there are only 4 playlists that you can configure on the BS5!!! You can only add songs to the 4 colour buttons.
The so called Numbered play lists, from 1 to 99 contain only one song, that is used as a seed for MOTS.
The user guide describes every feature and tells you how to do it from the BS5 and on the next page tells you how to do it from the Beo5. There is one exception: In front of Browse music… there is no instruction for the Beo5. I thought the way to remote control N.MUSIC on the Beomedia 1 or Beoport, if not perfect was much more complete!!! At least you could switch to Album 34, or Playlist 55, etc…
