Random factor, like a tractor

I fired up the MP3 Walkman this morning (no generi-Pod for me), hit 'random' and decided to document the first five tracks it played for me. These are they:

• "Blow Your Mind" by Jamiroquai, from High Times: Singles - a bit crap, if I'm honest
• "A Car That Sped" (Radio 1 session version) by Gene, from To See The Lights - more than a bit brilliant
• "Lenina" by The Vapors, from The Best Of The Vapors - though you're better off buying New Clear Days in my view
• "Wild Boys" by Duran Duran, from Greatest - every home should have a copy
• "Groovy Train" by The Farm, from Spartacus - memories of loose-limbed dancing

The purpose of all this was two-fold: firstly, it maybe gives an insight into me that you, (in)constant reader, may not otherwise get; secondly, it might make you think about trying to program randomness into an electronic device. Surely if it can be programmed into my erstwhile MP3 player's firmware, it can't be random?

Coding randomness - is it possible? How do you test it? Any thoughts?
