I use the Random Radio all the time, as I love revisiting my own library of albums. Once installed, it can be enabled/disabled anytime as you wish for any zone you desire. When enabled, it stays enabled and therefore is always ready to queue a random album for you automatically when there is nothing to be played in the queue.
It basically works like Roon Radio, except only for your library and you have an option to select that either full albums or just tracks are randomly queued for you.
