One may say that's what we're doing ... though not rigorously. Since transferring my collection to digital for streaming I have taken geek-ness to a new level! Initially, I was concerned that some of my ever-expanding classical works would not get a play and so some 4yrs ago started listing items played, soon extending this to soundtracks and other genres.
I don't automatically choose the longest-time-not-played scores but every so often print a list of those albums which have either not been played in the last 3 years ... or ever! I admit to having many CDs - ripped to NAS - which haven't been played (and I'm not counting the numerous CDs awaiting ripping ).
My better-half chooses almost entirely from said listing, whilst I do dip into the complete NAS library for a particular score/album.
I was amused to find that the most recent listing - a week ago - carried only one John Barry score ... and that I chose to play last evening: Beat Girl (1960) ... as it hadn't been played over my existing hi-fi set-up it sounded better than ever!
From the >3yr listing, this morning my wife chose Pino Donaggio's L'Anima Gemella (2002) ... enjoyable but it can wait another 3yrs without being missed
Like Stephen Woolston and others who already expressed their mind, I'd be entirely unable to listen again to all my CD's and couldn't find a fitting method anyway. I rather pick them according to my mood. Or I happen to check out some of them in order to select material for compilations I'm working on. Another case is the announcement of a new edition like happened with MBR's recent expanded issue of A FISH CALLED WANDA: I just took my old Milan CD and will give it a spin since I didn't play it for maybe 15 years or so. I know a friend who's frequently planning thematic cycles dedicated to a specific genre or composer. It actually has to do with the way we live, if we organize things all the time or not. I don't.
