The good old music player to play music in background of games, i remember playing games like Oblivion or Cod with music in the background it was so good it's on PS4, but wish it was on my Xbox One too.

Any features from Xbox 360 u want on Xbox One?

Hell yeah!
I ripped the soundtrack from Silent Hill 3 and used it as the background for Limbo. It was amazing! I even had certain tracks for racing games etc. I miss that.

So much yes. The only way to listen to music and play is snap which is cool when your in a part but its annoying playing with yourself and having to snap.

edit- you should put this on the xbox feedback site.

Ha ha thats brillaint, i might try that (on PS4 though)

Love playing with myself but never snap it, would hurt too much

I usually just listen to music on my phone if I do listen to music when I'm playing a game. But it'd be a cool feature to bring back.

And as for a feature I would want from the 360 would be offline achievements.. I think it's dumb that you have to be online to get achievements and sometimes they don't come through right away.

It would have to be MP3 compatible now. Nobody has CDs anymore.

xbox doesn't have that?

i was very happy when ps4 put in spotify support but i wish it also supported amazon music because that is the service i use normally. spotify ads are annoying. ...and i don't mean ads are annoying i means spotify ads are annoying. i swear there are only 5 ads total that just play over and over and over again.

You can run another app side by side with the game but, on Xbox 360, you could actually take a CD and rip the audio to your Xbox 360 HDD and totally replace your game's music with the soundtack of your choice.  In some games, like WWE, you could make your character's entrance music be something from your music library.  It was cool.
