A Long Time Ago, We Used to Like Your Theme Song

Why on earth did they change the theme song to Veronica Mars for the third season? I keep watching it, hoping that this week someone with the power to change it would restore what was the best theme song on network television these days. But it's not just that they changed, they changed it to a hollowed out shell of its former self, and so every week we're reminded of just how bone-headed the decision to change it was.
