Sony has just published an absolutely gigantic FAQ regarding a lot of key features for their upcoming Playstation 4 console. Lots of things we haven’t had clarified until now have just been made clear, so please read on.

First of all, now we know how Playstation 4 has an advantage over Xbox One – all disc based games must be cached to the harddrive disc, meaning the system has to use less resources to load things from the disc, leaving more muscle to push out that liquid smooth 60 FPS and 1080p experience.

What’s more, we previously had confirmation that the Playstation 4 wouldn’t play regular old audio CDs (that extra laser costs money), but now we’ve learned from this FAQ that the console won’t play MP3s or have DLNA support, and Sony boss Shuhei Yoshida is already on it:

Thanks for the feedback to the lack of MP3 and DLNA support at the launch of PS4. I'll share with the PS4 Dev team for future consideration.

The bit pertaining to this in the FAQ talks about playing music in the background, conveniently they’ve suggested that you can listen to music using their Music Unlimited program, but that requires extra money.

You can check out the FAQ in its entirety below:

• All PlayStation 4 Blu-ray Disc games must be cached to the hard drive to ensure a smooth gaming experience. However, certain titles may not require you to wait for the game data to be fully cached before starting gameplay. In order to start playing disc-based games, users will need to insert the game disc into PlayStation 4 just like on PlayStation 3.
• You will need to download and install PlayStation 4’s day-one system software update 1.50, and then activate your Blu-ray Disc video capability with a one-time activation through the internet in order to play Blu-ray Disc films and DVD video content. If you are not able or don’t want to connect your PlayStation 4 to the internet, you can call SCEA and request a Blu-ray activation disc.
• You can install the 1.50 day one update via a USB stick.
• The following PlayStation 4 features have been announced, but won’t be available at launch in North America: share controller via the internet to assist a friend, suspend/resume mode, wireless stereo headsets support for a wireless stereo headset, Pulse wired stereo headset, and Pulse wireless stereo headset elite edition.
• You cannot change your online ID on PlayStation 4.
• Sub-accounts work exactly like they do on PlayStation 3. In the case of a child, they cannot be changed to master accounts once the child is past the age of 18.

• A maximum of four users can be simultaenously logged onto one PlayStation 4. Multiple users, however, cannot make user of the automatic Trophy sync and Push Download services.
• The PlayStation 4 comes with a webkit-based web browser, which is faster and more compatible than the PlayStation 3 browser.
• It takes about two hours to fully charge a DualShock 4. Its battery life is similar to that of DualShock 3. They can be charged while the system is in standby, as well.
