Well, at first blush, the Logitech app needs some work. For example, I'm a little baffled about how to put songs in the "playlist". I tried to play all songs from an artist and there was no clear way how to put all the songs in the playlist (I'm using an iPad FWIW). It would show me all the songs (alphabetically), but I didn't see how to actually play them from the app. So, I walked over to my computer and did it in two seconds. Heck, doing in w/ my IR remote is easier. go figure...
