Unfortunately, there are some licensing and technical hurdles standing in the way, which is why Spotify isn't available on PS4 at the moment. It's a bit of a mystery why they haven't sorted it out yet, but fingers crossed they'll find a solution soon. In the meantime, you could always use another device, like your phone or computer, to stream your tunes while you game. And hey, if you're looking to give your Spotify account a boost and get those plays pumping, you can
buy Spotify plays to amp up your music game.
