Media Storage Problems

I am a person who has lived through the media transition from cassette tapes to cd's. I have not grown up in the world of digital music (where you download everything and never have a need to puchase a cd). Because cd's were the main music vehicle for the better part of my life, I have accumulated a ridiculous amount of them. I have stacks and stacks of cd's, and they have also gotten intermingled with dvd's as well. Some of them have the cases, but most of them do not. (I did realize that the cd cases were taking up way too much room!) 

 

I have one large binder with hundreds of cd's in it. (308 cd's to be exact.) This binder holds cd's that range from those that I got in high school, college and my own personal mixes I have made over the years. For some reason I really don't want to get rid of any of them...

As much as I would like to think I would take the time to download all of my cd's to my computer (and therefore be able to throw away all of the cd's), I will admit that is not a probable solution. I'm looking for some logical solutions for cd storage. The best thing I can think of so far is to get more binders and keep them in "volumes" of some kind - by decade, genre or some other category. I'm open for other suggestions. Any ideas?
