Stops displaying the duration

When I first purchased this app I was very happy to finally have found something that I needed so desperately. When the upgrades on the iPhone came along for some random reason this app stopped displaying the duration of the song randomly. Some songs work properly as expected and then you may play that same song again and the duration stops working so youll hear the song but you cannot stop it positive or see how long is left in the song. Very critical error for live performances.
