In an update that will probably have many saying "it's about time" Microsoft is finally adding background music as an option to the Xbox One. Right now, it appears that the function will primarily work with Pandora, but it's a step in the right direction.
Other features included improvements to the Cortana experience and addition of features you can use with the system. I haven't used Cortana much, but what I have used I've enjoyed! Let's hope they continue to improve things we like!
