Honestly I can't get behind this at all... alphabetical is the only way my brain works with physical media. I tried sorting my Blu-rays by "mood" once and spent twenty minutes hunting for a specific K-On movie because apparently I filed it under "cozy" instead of just K. Plus my shelf has guests over sometimes and nobody can find anything if it's not in some kind of logical order. I get the appeal of rediscovering stuff but I'd rather just flip through my own collection like a record bin and accept that I forgot some shows exist. That's half the fun for me... the surprise when I stumble across something buried in the back.
