Music Organization OCD

I never lend out my music much any more (except to my brother usually).  Unfortunately, the majority of people I know just download illegally what they want most of the time .  

My problem comes with DVDs.  I had a friend who would always return one I'd lend him in much worse shape than when I initially lend it in.  I'm even having DVD problems in my own house.  My younger sister would often borrow something, and I could never find it after then.  Right now, I'm still looking for an old Horror film DVD-set, The Omega Man, and Return Of The Jedi .  

In which case I have OCD and proudly lost my life to music decades ago.

Unfortunately, I have just lost an argument with my better half to set aside another wall for shelving to house my next line of album purchases. C'est la vie!

However, my mp3 collection is arranged by sub-sub (and in some cases sub-sub-sub) genre, alphabetically, with each folder and file name in a specific format.

So yea, you could say I'm OCD.

If I had the space, I'd get some nice shelving for my CD's and organize by alphabetical order and then by chronological order.  I don't need to make any hard decisions about what genre something goes in.

But I do have a particular way of organizing my vast CD collection. I organize them alphabetically by artist, and then within each artist category I organize their discography chronologically. I don't care that much about how my MP3 library looks, but I am VERY particular about my CD collection.
