I'm a musician, and have a folder full of songs in my repertoire. I used to strictly alphabetize, but now I use dividers lettered A-Z (hash table), with each letter organized alpha at first, but move-to-front whenever I perform a song (MRU). I can now often find the song I want in 1 or 2 lookups, which really beats binary search.
