Your music collection by the date

I've got over 1500 CDs now.  In about the mid '90's I started to log them in to Excel, but I didn't start including added dates unil 1999.  I was just doing an alphabetical sort every 100 titles and then numbering them in a batch.  I've never done an acquisition order listening exercise, partly because I haven't kept up with that but also because I don't find that mode particularly interesting as I already did that in real time.  Right now I'm doing a reverse chronological shuffle.  It's 1998, so I pull all of those titles into a separate spreadsheet and use the RANDBETWEEN function to pick the listening order.  Of course I'm not too anal about it.  I'll skip a title and come back to it if I'm not in the mood for it when it comes up, but I'll complete the year before moving on to the next one.  Again not being anal about it, I will intersperse the randomized revearse year listening with whatever the hell I want to listen to if I don't want to do the title the randomizer comes up with.  In the end my goal is to be sure that sooner or later everything gets listened to, or there's no point in having them in my collection.  Unfortunately the titles I would be most likely to sell of wouldn't fetch much.

Since some of my records are anthologies from bands or even record catalogues, it would be rather complex to range my records by the date: in which decade could I classify a compilation of Deep Purple or Black Sabbath going from the late 60's to nowadays?

OK, how much albums do you have?

I tried this a couple times back in the day but usually got bored before a single day was out, let alone how long it would take me to actually go through my collection chronologically.

I dont understand the question
