* The song [[http://www.youtube.com/watch?v=DCFtBlKDIaM "Siege of Madrigal"]], included as an easter egg in the final track of the ''Halo'' soundtrack. It would be even sadder if Bungie actually used it in the Halo series.
** It appears in each ''Halo'' game... [[EasterEgg if you know where to look]].
