Since installing 7.4.2 to my Windows Home Server, I can no longer use the Controller to add an item from my Favorites to what's currently playing. I can still press the center button and play the song, of course, but this replaces the whole current playlist with the song, it doesn't add it to the end of the list. When I press the + button, the context menu that pops up lists only "Title" and "URL", there's no option to add the song to the current playlist, remove the song from Favorites, etc.

I called phone support and was told this is now the way the Controller is intended to function! Has functionality actually been removed? 

Surely this is a bad thing. I (used to) add songs from Favorites to the current playlist all the time.
