Well, here's a practical example of the kind of things I've gone through. Over the years my family assembled, in addition to a significant number of Broadway and classical albums, a fairly large collection of high fidelity, open reel pre-recorded tapes. The tapes dated from the 60s and 70s, and outlived our Japanese reel-to-reel player. My father sent them to me and I was able to digitize most of them. Many of them were Gilbert & Sullivan Operettas done by the D’Oyly Carte, and recorded by London ffrr. So, for me they have been stored hierarchicly under “Gilbert and Sullivan” followed simply by title. I could have gone by order of composition, performance, etc. but title seemed to be all I required, until I inherited some older LPs and added them to the hard drive, so now I had different performances of the same operettas. I think I parenthesized the estimated dates for those.
