All the secret features of PS4 Firmware 4.0 seem to be coming out now and there are some pretty neat hidden extras.
Earlier we told you about the ability to find out the requirements of a hidden trophy, but another great feature is just how integrated Spotify is with the PS4 now.
For instance, when playing any game you can head over the quick menu and select Spotify. Doing this will bring up a playlist suggestion based on the game you are playing. Swap games and you'll get different suggestions. We think this is a great feature.
Here's a video we found explaining the feature via Push Square.
It's a great feature, don't you think?
