How do you sort your LPs?

Autobiographical

By genre (classical, jazz-blues, rock), then by composer-composition (classical), artist-composer all other. In classical, when there are more than 1 composer involved, I favour the better of (usually) two performances.

By genre, first, but in the classical category I just finished sorting by the labels.  Within the labels I have a good idea of the artists, composers and pieces.  I guess I'm thinking of selling down the road as I'm getting older and wanted to see if I had anything valuable.
