When I use another music player on iOS6, the whole musical environment of the iPhone adjusts to use that app. I mean, if I open the task panel, and swipe right, the icon of the app currently playing is there, and the controls work for that app. The same when I double tap on the lock screen. Why can Apple do the same with the camera, for example. Why can't we just set Pure camera or Kitcam as our default, and it will open it when swiping up on the lock screen? Same as with default browser.
