iMovie controls?

I can't figure out how to fade out a song at the end of a movie with iMovie. Is it possible? All I can do is add a song and then when the movie ends the song completely just stops. It'd make it so much nicer if you can easily fade the song over a few seconds before the end clip.

Thanks.

Also does anyone know how to make a song repeat after it ends? Can't seem to find that either.
