Get 4 Sony megachangers (they're cheap). If you don't want to use them for playing CDs, you don't have to. You can just use them for storage and retrieval, with an alphabetical listing on paper cross referencing to the changer and slot number.
What do you do with all those CD's??
I need some help deciding how to store my CD's. I have about 1500. My stereo is in the living room, so I need something that looks good but is practical. I've tried binders but found them such a pain to add new CD's and keep everything in alphabetic order. What is everyone using out there? Has anyone found a good solution?
