My problem is that after:
-taking only my favorite CDs with me to college so long ago (to avoid losing any to misplacement or theft)
-transfering between multiple vehicles and their CD changers
-buying new CDs at school
-transfering between CD book cases
-carrying a couple CDs in one case for convenience sake (bad for the CD)

I now have about 300 CDs in 2 or three different houses, 4 different cars, on loan to several people, sitting under furniture, and any number of other places. Several times I've tried organizing the largest single location of my CDs, but on closer inspection I find that half of the cases are empty and the other half are missing sleeves.

Organization is not my forte
