Don Satz's description of his method for selecting the music he is going to
listen to makes perfect sense and is an interestingly random way of doing
it.  I remember Don's unsuccessful efforts to alphabetise his collection
and I have no wish to revisit this concept, but I'd still like to know,
Don:  You're driving home from work and you have an urge to hear, say,
Brendel's version of the Schubert B Flat Sonata when you get home.  How on
earth do you know where it is?
