I'm not sure what you're after here. Why would you want media controls in the Notification Center? The media control box is already available when you play media. All you need to do is press on of the volume keys when the phone is unlocked.
IOS and Android have media in their notification bar and it just makes sense to have it. As opposed to listening to media, loading instagram and hitting the volume turns down the video volume not the media volume. And being able to adjust the volume or skip a song while reading notifications without the controls disappearing and having to press the volume again and again.
