If I sync some albums to the Music app on my iPhone or iPad I can't see just those songs that are resident on the device without having to wade through the several thousand that are in the cloud and available for download. In other apps such as the Audible app I can select to see what is in the cloud+device or see just what is on the device. I can't see how to achieve the same with the Music app. From a usability point-of-view it seems odd that this function isn't available. Not every one lives in an area of free and copious internet bandwidth.
