I am surprised this issue has not been raised before. The playlist function on Sonicstage seems to work OK. However on the player itself the story is different. If you have playlists the only view that makes any sense is the Goup view but have you ever tried to find an album in a none alphabetical list? In artist and album views the playlist tracks show as duplicate tracks on the original album making these views useless since all the albums containing favourite tracks have duplicated tracks. I use the artist and album views all the time since the lists are in alphabetical order. I have given up using playlists for this reason and lost what is potentially one of the most useful features of the NW-HD3. The problem may also be on the NW-HD5.
