I see.

That makes a great deal of sense.  I had wrongly assumed you were maintaining some kind of a full-sized table of recently used songs.

Which goes to show you how much I know, I guess.   

Obviously, implementing this would be a bigger undertaking than I had thought.

So, in the immortal words of some random Mafia guy, "Fuhgeddaboudit".

The utility is far overshadowed by the work involved in getting it going.  Really.

Thanks ever so much for the reply and the insight!
