The purpose of the Soup views is to relieve you of the need to create your own artist/album playlists.

The empeg guys said that they will definitely be giving us a way to select soup items from the main menu, it's just not in 2.0b3 at the moment. So for now you still need to create playlists as you always did. At some point in the future, you won't need your artist/album playlists any more.
