you can stream music from your pc to the xbone, I'm not sure if you can still listen to it in-game like the 360... but I don't see why you should'nt

I mostly prefer old school style couch co-op, some of the enjoyable ones that have rpg elements of upgrading character abilities/traits are the Marvel Ultimate Alliance games and Castle Crashers.

The only live streaming events right now on the ESPN Xbox app are "ESPN3 " broadcasts only. The "Watch ESPN" feature that includes all of the normal ESPN game broadcasts (ESPN, ESPN2, ESPNU) is going to be added to the Xbox app later this year, presumably with the Fall Update. All of your questions are answered on ESPN3.com FAQ's section.

What's your internet/cable provider?

I'm curious about this game as well.... specifically the offline co-op. How does it compare to games such as Castle Crashers and other action-adventure/beat em ups where you can play with a friend? This sale on XBLA has me interested,

Get a used copy of ODST from Gamestop for $10 because it comes with a separate disc that includes the entire Halo 3 multiplayer and all of the DLC maps are on it. I did this about a month ago and theres still a sizable online community for the game. If you went out and bought the normal Halo 3 game for 5 bucks, you would have to also shell out about an extra $20 or something to buy all of the DLC which would be incredibly stupid. Just get ODST used for $10 to have access to the entire Halo 3 multiplayer and all of the playlists.
