Interesting question. For the reasons stated above, I now organize strictly alphabetically (it can be difficult to classify some artists/albums by genre as they do tend to overlap).
That said, and notwithstanding some of the interesting ways of organizing albums that have been listed here (e.g. geographically, best to worst, etc.), I have a friend who organizes his albums (about 2000 of them) chronologically, not by the year the album was released, but by the year and date the album was purchase. So, the first album was his first purchase and the last album his last purchase. How he can keep a road map of this in his head boggles my mind.
