Can I install Songbird media player as the default on a Window 7 WMP laptop?

A story. A man fires a rifle for many years. and he goes to war. And afterwards he comes home, and he sees that whatever else he may do with his life - build a house, love a woman, change his son's diaper - he will always remain a jarhead. And all the jarheads killing and dying, they will always be me. We are still in the desert....
