If we're thinking of the same song, it's actually just called Halo. After Echo 419 crashes, the song starts at about 40 seconds into that video.
I'm thinking of a different song. If you stick around long enough, the ending of the song is hauntingly similar to Halo 3's 'One Final Effort', played during the final Warthog Run.
That is the right song.
