Congratulations on this downsizing achievement. I have six boxes of CDs sitting next to me, awaiting some new media shelf to house them. I don't think I'll be ready to take this step yet. Did you really weigh it the empty cases? How many digipack CDs did you end up with, where'd you have to throw away the whole package in order to downsize?

~600 empty jewel cases will indeed weigh about 100 pounds. seems like around 10% were digipak which i keep for now. i got 3 of those large ~300 capacity heavy nylon folders with 4 per page. cds go into top row, bottom row holds tray insert first then jacket over it. fits easily sideways. flattened insert sticks out some but because its on bottom row it works, and when you pull out cover jacket you can see the insert with song list underneath. this method reduces physical space of collection by about 75%, allows me to keep all the art, eliminates dust, and makes browsing easier. $100 price tag.
