After reading a notification, media does not restart about a2dpvolume HOT 2 OPEN

I thought I replied to this and just noticed I had not.  Sorry about that.  

I use some common methods to manage the pause and restart of the music.  
Unfortunately it seems that different players have used these interfaces 
differently.  Pandora is the worst.  They seem to change it too.  I can't keep 
up.  I tried for a while but every Pandora release seemed to bring another 
change that broke things, mostly with launching a specific play list and 
closing down the player.  Google Play Music often just puts the music in the 
background while the text reads.  Others do different things.  I was able to 
get Google Play Music to work correctly.  I now use Google Play Music as it 
seems to work best and I also like the instant mixes for driving since it 
requires far less driver interaction.  It also works good with voice commanding 
music (finally).

Since the players work differently, just toggle the pause on the Bluetooth 
streaming control for now.  I will look into a better solution when I update 
for lollipop.
