Control Music From Notifcations Bar
Unfortunately, there is no built in way to do this with iOS 6 (or lower).

There are other ways to control music playback that may function as a work around for you. 


If the device is unlocked, double tap the home button and swipe the row of apps from left to right. This will display Play/Pause controls. Swipe one more time - on an iPhone or iPod Touch - for volume control.
If the device is locked, double tap the home button. This will display music controls.
