Xbox One won't get background music until summer at the earliest

Phil Spencer admitted as much in answer to a question on Twitter.

Would it be nice to play your own songs through your Xbox One without having to use a second window? Unfortunately, the console doesn't support background music, and that feature isn't coming until Summer. Xbox head Phil Spencer was asked as much on Twitter, and responded that it wouldn't be "before Summer, sorry to say." So, that's that, and you might as well get used to having only 80 percent of your TV's real-estate taken up by your game, since Groove Music is keeping the rest... for now.
