.......I'd flip. That song has been in every Halo game (except Wars) after CE; it was original from Myth (another game by Bungie).
I realize the song is kinda Bungie's song....but I think it would be a wonderful idea of 343i included it in the next Halo games as a 'tribute' to Bungie. :(
You can listen to the song here: Siege of Madrigal
