I knew you guys would come up with some more functionality. Here's the addendum:

• QUEUE - Removes everything left in the queue, leaves the current song playing, takes whatever you select from the Playlists menu, keeps it in order, then adds it to the end of the running songlist.
• QUEUE SHUFFLED - Removes everything left in the queue, leaves the current song playing, takes whatever you select from the Playlists menu, shuffles it, then adds it to the end of the running songlist.

Additionally, "Replace" should be renamed "Play" editing above spec, now.
