Great App, but conflicts with sounds – States And Plates Free, The License Plate Game Review

This App is great for keeping track of the states. What I don't like is that if I'm listening to an audiobook or other sound on my phone during a trip that it conflicts with that sound. Would be nice if you could continue to listen to the other apps while this one is open.
