How to view the songs actually loaded onto the Gear S2

[AC Question]

I am able to transfer music from the phone to the Gear S2 without a problem. But how can I see (on my phone) all the songs that I have transferred? I'd like to not only view what's on my watch, but also how much memory is left on the watch. There does not seem to be a way to do this. It's kinda like I'm blind to what's really on the watch.

Is there a way to use my phone to view all the files I have moved to my watch and see how much memory is remaining on the watch?
