It's really a David Caruso prejudice, since I have zero corresponding prejudice for female redheads. My best friend is a flaming carrot top. ;)

I'll keep my ear out for songs. The first thing that pops in my head is actually an instrumental called "Life In Technicolor" by Coldplay. It's quite short, but it has a slow build and feels tonally appropriate -- it's a little melancholy, but it celebrates life, which is how the show came across to me too.
