S Voice won't play music on Galaxy S7

[CompostBin]

I have a Samsung Galaxy S 7 that is only 1-2 months old. I added an SD card and S Voice worked fine for playing music via Google Play from my card. Out of nowhere it stopped. Every other command works, but not the "Play Music" command. It will display my command, so I know it is receiving it, but nothing happens. For example, I would say "Play Bob Dylan" and it would shuffle through all the Dylan albums on my card. Now it just display the command and t hat's it. Anyone able to help?! Thanks.

( I also just installed the latest software update, but that did not help)
