I don't know what devices you have, I have a 1520, Surface Pro, Laptop, desktop and Xbox One, your music pass is good for 4 downloadable devices, as the Xbox One doesn't download it doesn't count so all my devices work with the pass.
I have copied all my local music to each device, get all of that sorted then take out the pass, then any album you add to your collection will show up along with all your local music, but you can easily find out what is the music you have gained by the pass by setting it to show your cloud music.
As mentioned I am more than happy with the value of the pass.
