Yes, I have to double tap home button to get the apps that are open at the bottom (or swipe with four fingers)and then I turn off the iPod app by holding it until it jiggles and then deleting it. This clears the problem but it can do it again although not every time. I think it's a bug but at least I can clear it by doing the above. Before the ios5.1 update, I had to reset the iPad. So clearly they must know there is a problem and corrected it. If you look at the thread I suggested, you will see that Richsadams, myself and other members are all not happy with this new music app. We live in hope of the future corrections.
