what's your favorite song?

Hey!! It's Friday...Everyone should be winding down for the weekend, right? I don't think there is such a thing as winding down...anyway....what's your favorite song? Why do you like it so much? Has it inspired you in some way? Does it encourage you? I think my all time favorite song is Amazing Grace. Don't ask me why....it just is. Everyone knows that song. It's sung in almost every language. It comforts me when things go wrong. It excites me when I'm happy. It's just a good ol' song. If you don't have a favorite song, you should.
