One of my retirement goals (a few years out yet) is to catalogue my collection in excel, where I can list the artist however I think best, can add columns for genre and sub-genre, etc. I played a little bit with the discogs collection feature a few weeks ago, found it just didn't meet my needs. I will probably write out instructions for my heirs on how to optimally liquidate my collection when I'm gone. My daughter says she wants to keep it, but I don't really see that happening.
