^ Totally get you, but I guess I'm lazy with everything that involves keeping track of things
At one point I used to have a spreadsheet similar to yours, the problem is that I never updated it once new things arrived, and then it got to a point where there was too many things to add and I was too lazy to do it hahaha
But soon I'll have to reorganize all my CDs (I had a whole closet removed from my bedroom and it's going to be replaced with a new one I'm going to use to store my CDs, so they're all currently in boxes >_<)... I guess it's going to be the perfect time to go through all of them and make a new spreadsheet...
