Hi Matt,
Just got around to installing the full version as I saw it pop up this evening. I like the functionality and it does seem to clear up some of what I was experiencing previously. I have noticed a couple of peculiar things:
If I start by adding stuff to a queue without having a track playing first, then go to play, a message comes up in iTunes that says: "You are about to start playback. Do you want to clear the 35 songs previously added to Up Next?" with the choices Play Song, Cancel, Clear Songs. No control from the remote device running Signal can then be used as there's a prompt on screen that must be cleared. Choosing Play Song will play the first song in my library, then the Up Next queue. Cancel ignores everything and doesn't play. Clear Songs clears everything I've queued and starts playing in library order.
OK, so I figure instead of queuing first before playing, I'll start playing first and then add things to the queue.
if I choose Play Now to start an album going, and then start adding other things to the queue, the additions insert themselves so that they play before the upcoming tracks from the first album. Example: I choose Pet Sounds to Play Now, it starts going like this:
Pet Sounds song 1
Pet Sounds song 2
Pet Sounds song 3
etc.
While Pet Sounds song 1 is playing, I choose Revolver and say Add to Queue. My playing order now shows:
Pet Sounds song 1
Revolver song 1
Revolver song 2
Revolver song 3
etc.
then
Pet Sounds song 2
Pet Sounds song 3
etc.
Adding another album or song to the queue adds after Revolver but before the remainder of the Pet Sounds tracks.
When I take a look in iTunes, the Up Next section shows everything I started with Play Now as "Music" and everything I chose to "Add to Queue" as "Up Next".
Neither of these methods is quite right. Of course there are ways to work around them, but so far it usually requires me to hear the mistake first and then jump to Signal to figure out how to correct it.
Thanks for keeping up with all this - let me know if you find anything out here.
