iPod random album trick

I often listen to my iPod on random. I vary listening modes from song to album shuffle depending on how I feel at the time. Today I wanted to listen to albums While setting up the iPod today I discovered a new (to me) trick.
If you do not like the starting album you can click the previous track button which will stop the playlist (because you are on the first track) and you can start over. To do this you need to make sure the settings are: shuffle - albums, repeat - none. Also I start the playlist by selecting music and clicking play; I have removed podcasts and audiobooks from the main list and enabled them as main menus. (this can also be done in settings)
