Some songs, just off the top of my head: "The Boxer" by Carbon Leaf (which has moved beyond an Unfinished Business song for me and into purely Kara), "Not Ready To Make Nice" by The Dixie Chicks, "My Skin" by Natalie Merchant, "Cinder and Smoke" by Iron & Wine, the Firefly theme song ("You can't take the sky"), "Boys Wanna Be Her" by Peaches, "Want Me Back" by Quincy Coleman...
