I have a mount in my car for my iPod touch but find it difficult to control when it's sitting there horizontally. For example, when I want to go from song to song I have to scroll through each album/artist and pick the song individually, as opposed to being able to just click "next" and go to the next song. Is there an app, maybe controller, etc that makes it more user friendly while sitting horizontally? I appreciate all you help in advance.
