How do you sort your LPs?

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.

By color! 
It's a thing we started in college with several room mates, decades ago.  Amazing how well it worked!  And still works.

Completely random.

bin for each genre, then by alphabet in each bin

Grouped by genre, then sorted alphabetically by name of band or last name of main artist. After that random within the band/artist.
