On sasung galaxy S5, will music on my memory card play using the google play app?

[AC Question]

My device memory is very near full and I would like to add some music to my memory card, but I am not sure if the music will play seamlessly with my current app. For example, if I have music on my device and on my card, when I press shuffle on my google play app, will it shuffle betwen the device and the memory card?
