Alphabetically starting with the first letter towards the side facing me. Could be the title of the album or the name of the artist. Therefore listening is completely random. I guess I could just put them all in randomly and would be the same effect but this way I feel there is a method to the madness. So if I know I want the listen to Selling England by the Pound by Genesis, I know it will either be in the “S” section or the “G” section.
