Say, what's the big idea?

A beautiful, sunny, cloudless morning for the walk to work today.

This presents a slightly odd problem though - what music should I listen to?

• happy bouncy stuff to complement the skies?
• slightly depressing stuff as a contrast to make me appreciate the day more?
• acoustic music - does that fit better with the day (it seems more natural or organic, like the sun)?
• heavy, distorted guitars and roaring vocals, for the opposite reason?
• stand-up comedy?

As I have an mp3 player these days, with about two thousand tracks on it, all the above options (and more) are available to me without much hassle.

What did I go for in the end? Random (or Shuffle as Sony insist on calling it) - just no way to decide.
