How do you sort your LPs?

Alpha.
Genre is too hard as Eric says, too many artists fall into possible 2 or 3 genre's depending which way the wind blows.

I suppose it also would make a big difference according to the size of your collection and how often you add to it.

Genre, then alphabetical order

Remember the scene in Diner in which Daniel Stern's character reads his wife (played by the delicious Ellen Barkin) the riot act for mis-filing one of his LP's? She put it away in the incorrect genre. Great movie, great scene.

Alpha by artist.  If you want to catalog them, consider putting them into the Discogs database.  You can then download a CSV file from Discogs.

I took the time and trouble to catalog all my media into discogs over a couple month time period following my thread on how best to catalog music from a couple years back.
However I did NOT know you could dl it as a csv file, interesting and thanks.
