The only way to move through menus is to touch the scroll bar. This is suitable for short menus but will be a problem for browsing through long lists of music. While intuiting the size of the list from the length of the scroll bar indicator and then touching the bar in the right place to jump to the desired place in the list is a skill that can be learned, best not to make the user have to learn this. Arrow buttons or another mechanism should be provided to single-step through a list and to provide press-and-hold functionality.
