In the iPhone version you can jump from any playing track to songs from its artist or its album. This does not exist in the iPad app. This is an important feature and must be added.
If you press and hold on a track, a menu drops down where you can go to the artist. Or if you are in the full screen artwork view, if you tap once you can see it also. Doesn't appear to be a way to get to the album though, just the artist.
