What Is Your Favorite Song On Super Mario Galaxy?

I have to say Super Mario Galaxy displays some of the most nicest songs. What song is your favorite from Super Mario Galaxy? I personally fell in love with the song for Good Egg Galaxy, simply the best.

Also does anyone know the song from Super Mario Galaxy at the end and what it is called? It's not the credits, it's the song where Mario is riding on th Grand Star and then he grabs peaches hand and flys with her, does anyone know the name of that song? Is it Good Egg Galaxy's song as well?
