R6700 readyshare USB media server

I've attached an external hard drive to the USB port of my R6700 nighthawk and can view/play media files through the Netgear Genie app on my iPhone and iPad.  I would like to access music files through a "jukebox" interface (iTunes-esque) rather than a file explorer type GUI.  Is this possible?  If so, how?

Thanks in advance.
