(^ check link above for the text below) If you want to use the soundtracks or audio effects from the original game, we often license those from or to third parties and don't always have the rights to pass them on to you. If we do, we'll let you know.  For example, we might mention on the community website for a particular game whether you have these rights, so you'd do well to check. If we don't let you know, you need permission from a third party, especially for games with licensed music. But we'll confirm right here that the music from Halo 3 is available for your use in non-profit ventures thanks to an arrangement with O'Donnell/Salvatori, Inc., composers of this iconic theme.
