Do I own that CD? One possible solution

One possible solution, obviously, is to get rid of all your CDs, then you know the answer to "Do I have this already?"

Not finding this an acceptable option, I have, as a time waster, embarked upon the effort of creating an Excel spreadsheet to catalogue my music CDs, with the intent of expanding it to include cassettes and LPs as well. A maximum of ten data points per record, such as composer, director, artist, album title, issue and reissue dates, labels, format and media.

Having started on this yesterday, I already have 116 entries, which looks to be about a third of the CD collection.

Oh, the reason for using Excel instead of OpenOffice for this is quite simple, my PDA will open Excel files, so I can take this list with me.

While at a certain level this is the silliest thing I could be doing, especially given not going out to buy CDs so not being concerned by the question, do I have this already?, it is giving me a sense of accomplishment, and is reacquainting me with my collection, which I had utterly ignored for the last five years; when I go into an isolationist period, I go into an isolationist period! And unlike other recent activities, this isn't making me melancholy.

So, that's what I've been doing the past two days.
