How do you arrange the order of your records?

Alphabetically by first name of a band but by last name if it's a person's name. 

eg, The Black Crowes is before Jackson Browne. ("the" doesn't come into play with my system)

Genre, then artist with the exception of a section containing about 50 of my current, go-to albums with the most recently played disks on the right, so I can mix it up a bit and not over-expose any to the point it needn't be in the go-to section.

Chaos.  Hunt and discover.  1500 vinyl and 3500 cds,  all CDs displayed horizontal so the titles can be read in the storage drawers and rack.  If I want a specific disc, I stream it via Quobuz or Idagio.  Hi-rotation CDs make a small pile in a shelf.  I do not have the energy to create an organization.  Having search the vinyl so many times, I have a rough idea where some records are. 

Three groups, single album by Artist/alpha, and multiple albums by Artist/alpha/order of release all mixed genre. Jazz in its own territory.

My LP collection I divided into categories: Comedy/Spoken Word; Folk/Ethnic Music; Show Tunes/Original Cast/Soundtrack Albums; Classical; Jazz; Rock/Pop, all alphabetical within each section. From the start with my CD collection, I just lumped all music CDs together alphabetically, the only ones separated out into a separate category being spoken word. I store CDs in Leslie Dame spinner towers that hold 1000 discs apiece, of which I now have four, the fourth half full at this point. My greatest eccentricity is that I sort discs alphabetically right to left instead of left to right like a Christian, as if you stacked them on top of each other and turned them on their side. I sort my books the same way. Why I started doing it this way is lost to the fog of time except that it just seemed logical to me.
