Xbox Music + Xbox Video app updates

Looks like the Xbox Music and Xbox Video apps were just updated (though they may take a while to show up automatically, like usual- check the Settings charm, and then App Updates, and manually check for updates to get them immediately).

The changelog doesn't appear to have been updated yet, but I don't personally notice much that's different in either app. Maybe Music feels a touch faster, but it was improved a ton in the last update and if this is faster, it doesn't feel as dramatic.

But if anyone else figures out what the differences are, that'd be nice to know.
