I have noticed that when I ask for an artist, then look at the playlist and ask for a song, it usually plays the wrong number in the playlist. The command is understood correctly by looking at the voice control app window. BlueZx3 also noticed then when we were testing it last night. He saw in the live debugger that it was requesting to play song 23 in the list, when there were only 10 songs total in the list.
Other than that, it is working amazingly! I have the skin just about all voice enabled now. Just a few more things to add and tweak
