iPhone 5. New guy having problem getting to music library quite often. My audiobooks are in music library(another issue?) and after listening to one, I can't seem to get back to library many times. Best procedure or is there an app that I can use?
Any help would be greatly appreciated. Please ask questions if you need more information.
