In a recently posted long Q&A section on PS4, Sony has confirmed that its upcoming gaming console is now DLNA compatible and it won’t be able to play audio CDs as well. Even though you can ignore DLNA compatible thing, I don’t know why Sony has decided to stop supporting MP3/Audio CDs. Anyway, Microsoft has confirmed to Penny Arcade that Xbox One will be DLNA compatible and it will support Audio CDs as well.
The system is also DLNA compatible, and they’re in the process of being certified. As for mp3 playback… well, that’s kind of a mixed bag. The system is a Play To receiver, so you’ll be able to stream your content to the Xbox One using any Play To supported devices such as a Windows 7, 8, or 8.1 enabled PC, Windows Phone, etc.
So it doesn’t seem like there is going to be a way to simply import your music files, but you will be able to stream the content you already own, hopefully use it in custom mixes for your game, and the device will be DLNA compatible. Audio CDs, for the people who care, will be supported.
