I created a new list under Audio on my MC but I can't get it to show on my iPad list.
Under Audio, the items are called Views. They can have Panes, Categories, etc. These are meant as organizational structures to show large portions of your library, perhaps the entire library. Just organized a specific way. Is that what you meant to do? Or were you just trying to create a playlist? If you just want a playlist, create it down below under Playlists and it will show up automatically on the ipad.
If you really wanted to make a new View, you can show this on the ipad too, but it requires a different procedure, which I can describe if necessary.
