Music App for Samsung QE55QN94AATXXU

Samsung QE55QN94AATXXU. 

Is there an App I can install on my TV to allow me to play music from a portable drive? I want to set up playlists and use other App features.

Is your portable drive WiFi, then you can mirror it, if its USB just plug it in , you also then have the option to listen to music with the screen on or off but still have music

Thanks, I should have made it clear that I want to set up playlists and use other App features.
